Sidestream 

CO 2 Option 

The RESP option detects the rate or absence of respiratory effort, and is configured with 

the Pulse Oximetry option. 

The Expansion Module with Printer (EMP) provides a lightweight 3-channel recorder.

Reference Guide Getting started 9 

Propaq-to-Acuity ® option 

This option allows communication between the Propaq Encore and the Acuity Central 

Monitoring System by means of an ethernet network system installed in your facility. The 

Acuity System operator can view the patient data and control most of the bedside Propaq 

functions. The Propaq Encore connects to the Acuity System through an Acuity network 

cable that plugs into the Propaq right side panel. 

Modem-Propaq option 

This option allows telecommunication between a Propaq Encore and the Acuity System 

by means of external modems. This option is configured with the Propaq-to-Acuity option. 

For more information refer to Modem-Propaq Reference Guide. 

HP-compatible side panel option 

The HP connector-compatible option makes the Propaq Encore compatible with many 

Hewlett-Packard sensors and accessories used with the Hewlett Packard Component 

Monitoring System. This option replaces the standard Propaq Encore left side panel.

WARNING Before you use a Propaq on a new patient, always turn off the Propaq 

for a few seconds, then turn it on again. This clears the prior patient’s trend 

values, alarm limit settings, and NIBP cuff inflation target. 

1. If the Propaq Encore has been used for a previous patient, switch the monitor off, 

then on again. The monitor will turn on in the powerup patient mode with the 

associated settings. 

Note 

Verify that the powerup tone is produced. If the monitor has SpO 2 , verify two 

tones are produced to make sure that both speakers are working. 

2. Verify the monitor is in the correct patient mode according to the patient’s age. If the 

patient mode is not correct, change it. (See “Monitor setup” on page 20 to change 

the patient mode.) 

WARNING Always check the patient mode when monitoring a new patient. The 

patient mode determines default alarm limits, maximum cuff inflation pressure, 

and internal algorithm settings. 

3. Verify the battery voltage is sufficient for monitoring. If it is less than 7.4 V, connect to 

a power adapter (see “Power adapter intended use” on page 89 for information about 

the power adapter). 

Power-up equipment alert: program fault, settings lost 

If a PROGRAM FAULT: SETTINGS LOST, TIME/DAY RESET equipment alert appears when 

you turn on the monitor, the monitor cannot recall the programmed custom settings and 

current time and date. This can occur if the battery is drained or after new software has 

been installed. 

If this occurs, the monitor provides a special sequence of display windows to help you 

regain use of your monitor as quickly as possible. Do the following: 

1. Connect an ac power adapter to recharge the battery (if the battery is drained).


2. Press any button below the equipment alert screen to acknowledge the alert. The 

monitor will display the Mode Setup window (shown on page 23). 

3. Press these buttons to select one of the Factory patient modes for use: 

Factory Adult mode 

Factory Pediatric mode 

Factory Neonatal mode 

POWERUP*, YES. 

NEXT, POWERUP*, YES. 

NEXT, NEXT, POWERUP*, YES. 

After you press YES, the monitor will display the Time/Day window. 

4. Press NEXT, UP, and DOWN as needed to set the time and date. Then press ENTER 

to store the new time and date. 

Note 

These display screens are only displayed in this order if the PROGRAM FAULT 

equipment alert occurs. 

5. Turn off the monitor, then turn it on again so the settings will take effect. 

The monitor is ready for use. If you want to store some customized patient mode program 

settings, refer to page 23. 

If you follow these steps and the equipment alert reappears at powerup, the monitor may 

need to be serviced and the battery replaced. Contact a qualified service person.

Propaq Encore display 

The display shows waveforms, vital sign numeric values, Propaq Encore status, and alarm 

information in different windows. Different vital sign numeric values (such as heart rate 

and blood pressures) have upper and lower range limits. If the Propaq Encore detects a 

vital sign value outside of the Propaq's measurable range, the monitor displays – – – 

(below the range) or + + + (above the range) instead of the vital sign value. 

WARNING The Propaq Encore will show + + + for HR numerics between 301- 

350 beats per minute. Above 350 beats per minute, it may display incorrectly low 

heart rates, due to intermittent picking of R-waves. 

Note 

Due to differences in software versions and standards required by different 

countries, the displays shown in this reference guide may be slightly different 

than the display on your Propaq Encore.

Setting the current, custom, and power-up modes 

The Propaq Encore has two sets of patient mode settings: 

• Factory patient modes. The powerup settings and alarm limits for these patient 

modes are preset and cannot be changed. They are listed in “Factory default 

settings” on page 118. 

• Custom patient modes. You can customize the power-up settings and alarm limits 

for these patient modes. (See SAVE on page 24.) 

WARNING If any alarms are set to OFF and you select SAVE to store the 

settings for that CUSTOM patient mode, those alarms will be OFF whenever the 

Propaq powers up in that CUSTOM patient mode or when that CUSTOM patient 

mode is selected. Consider carefully before setting CUSTOM patient mode 

powerup alarms to OFF.


Note 

The alarm for apnea cannot be turned off at any time. 

You can program the Propaq Encore to power up in any of the Factory patient modes or

Learning the Propaq Encore 

Using in-service mode 

You can practice using the Propaq Encore without a patient simulator by using the 

Propaq's in-service mode of operation. The in-service mode cannot be activated while you 

are monitoring a patient. The message “SIMULATING” alternates with the time of day 

and patient mode on the display. 

To begin practicing with your Propaq, disconnect all patient cables connected to the 

monitor. Leave the cuff connected so you can take NIBP measurements. If you have been 

monitoring a patient, turn off the Propaq Encore and turn it back on. From the Main Menu, 

press SETUP, WAVE SEL, INSERV. 

The Propaq Encore has two sets of simulated patient information—an initial set and an 

alternate set. To change between them, press the INSERV button again. 

If you connect a patient cable or set the NIBP channel to automatically take pressure 

measurements, the Propaq Encore stops simulating, goes through its powerup tests, and 

erases any simulated trend data it might have stored.


What you can do with in-service mode 

NIBP 

Printer message 

While using the in-service mode, you can press any of the Propaq Encore buttons, except 

for the AUTO/MAN button in the NIBP Menu, to change a function setting. You can also: 

• change the ECG and RESP waveform sizes 

• set alarm limits and cancel alarms 

• STAT SET alarms 

• customize the Propaq Encore settings 

• change from °F to °C 

• simulate invasive-pressure zeroing 

For noninvasive pressure measurements, keep the Propaq Encore in manual NIBP 

operating mode and take pressure measurements by pressing the START button. You can 

also press the NIBP Menu's TURBOCUF button to consecutively take pressure 

measurements for five minutes. 

Simulated data can be printed on the Propaq Encore Printer. All printouts include the 

message “SIMULATED DATA” every four inches to prevent simulated data from being 

mistaken for actual patient data. 

What you cannot do with in-service mode 

• You cannot use in-service mode to calibrate the monitor. 

• You cannot set the Propaq Encore to take automatic noninvasive pressure 

measurements (except Turbocuf) while using in-service mode. 

• You cannot use Defib Sync or Real-time ECG output while using in-service mode. 

• You cannot activate in-service mode if you have been monitoring a patient. 

Confirm and learn alarm behavior in the in-service mode 

To confirm that a Propaq monitor is properly generating patient alarms and to learn the 

alarm behavior of the Propaq Encore monitor, perform the following steps. 

1. Disconnect all patient cables from the Propaq monitor. 

2. To temporarily remove customized alarm settings, press the MAIN MENU key, then 

SETUP, MORE, CHANGE, SETUP, USE NOW, YES. 

3. To put the Propaq monitor in (non-alarming) Inservice Mode 1, press MAIN MENU, 

SETUP, WAVE SEL, INSERV. 

4. To set the Propaq monitor in (alarming) Inservice Mode 2, press MAIN MENU, 

SETUP, WAVE SEL, INSERV. 

Within 3-5 seconds, the monitor will alarm because the “patient’s” vital signs fall 

outside of the alarm limit ranges.


5. Confirm the following: 

The monitor is sounding an alarm 

A vital sign numeric is flashing 

The small red light in the top right corner of the monitor is flashing 

The SILENCE and LIMITS keys are showing on the screen 

6. To silence the alarm tone for 90 seconds, press or SILENCE. 

Visual alarm indications remain, and the alarm tone resets after the 90-second silence 

period. 

7. To bring the Propaq monitor back into the (non-alarming) Inservice Mode 1, press 

INSERV. 

The “patient’s” vital sign readings will return to acceptable levels within the alarm 

limit range. 

8. Turn off the Propaq monitor. 

Any previously set custom patient mode settings are restored when you turn it on 

again. 

Under these conditions, if the monitor fails to generate visual or auditory alarm 

indications, carefully repeat the above steps. If the monitor is still unresponsive, remove it 

from circulation and take it to your facility’s biomedical service department for evaluation.

Patient monitoring 

ECG/RESP 

Intended use–impedance pneumography (RESP) 

The Respiration channel is intended to detect the rate or absence of respiratory effort, 

deriving the signal by measuring the AC impedance between the selected terminals of 

the ECG electrodes. RESP displays a respiration rate and waveforms. Two respiration lead 

selections are available, Lead 1 (RA-LA) and Lead 2 (RA-LL). 

WARNING Impedance pneumography detects respiratory effort via changes in 

chest volume; therefore, impedance pneumography can be used to detect central 

apnea. However, apnea episodes with continued respiratory effort, such as 

obstructive apnea and mixed apnea, may go undetected. Always monitor and set 

alarms for SpO 2 when using impedance pneumography to monitor respiratory 

function. 

WARNING With any monitor that detects respiratory effort via impedance 

pneumography, artifact due to patient motion, apnea mattress shaking, or 

electrocautery use may cause apnea episodes to go undetected. Always monitor 

and set alarms for SpO 2 when using impedance pneumography to monitor 

respiratory function. 

WARNING The Propaq Encore automatically rejects cardiovascular artifact 

(CVA). This function is dependent upon accurate ECG R-wave detection. 

Therefore, always select the ECG lead with the most prominent QRS complex 

when monitoring respiration via impedance pneumography. 

WARNING Don’t place the Propaq Encore monitor with RESP in close proximity 

with another respiration monitor because the RESP measurement frequencies 

may interfere with one another. 

WARNING Because pacemaker pulses in some instances may be falsely 

counted as breaths, impedance pneumography is not recommended for use on 

paced patients. 

Note 

Impedance pneumography is not recommended for use with high frequency 

ventilation. 

Since RESP is derived from the same leads as the ECG channel, the Propaq 

Encore determines which signals are cardiovascular artifact and which signals are 

a result of respiratory effort. If the breath rate is within five percent of the heart 

rate or a multiple or sub-multiple of the heart rate, the monitor may ignore breaths 

and trigger an apnea alarm.

30 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor 

Intended use–ECG 

The Propaq Encore is intended for ECG monitoring of either a five-lead or three-lead 

configuration, including the Marriott configuration 1 (MCL1 requires all three electrodes). 

The five lead configuration can derive one of seven user-selected signals, Lead I, II, III, 

aVR, aVL, aVF, or V. 

The monitor will automatically determine if only three lead wires are connected, and will 

automatically reduce the number of selectable leads to three (I, II, III). If four-wire ECG 

cables are used, they will be handled as if they were three-wire cables. 

WARNING The Propaq Encore monitor does not have automated arrhythmia 

analysis, therefore, some ventricular tachycardias and ventricular fibrillation may 

not be interpreted correctly and may display an inaccurate heart rate. 

The Propaq Encore 200 series does not have automated ST segment monitoring, 

although with ECG set for extended bandwidth, ST segments may be accurately 

displayed and printed. 

The Propaq Encore ECG’s bandwidth is 0.5-40 Hz in Monitor Mode and 0.05-40 Hz in 

Extended Mode. Monitor Mode is useful to minimize baseline wander due to respiration 

or other artifact. However, in Monitor Mode, ST segments can be distorted, potentially 

causing underestimation of ST elevation and overestimation of ST depression. Always use 

Extended Mode when observing ST segment morphology on the display or printer. 

The Propaq Encore can be used during procedures using electrosurgical machines and 

defibrillators. However, even though the ECG channel contains electrosurgical 

interference suppression (ESIS) circuitry, noise artifact may be displayed on the ECG trace 

while an electrosurgical device is in use. This will vary depending on ECG electrode 

placement and the operative site. 

WARNING High-intensity radio frequency (RF) energy from external sources, 

such as an improperly connected electrosurgical unit, can induce heat into 

electrodes and cables which can cause burns on the patient. Reading errors and 

damage to equipment may also result. This hazard can be reduced by (1) avoiding 

the use of small ECG electrodes, (2) selecting ECG electrode attachment points 

remote from the surgical site and from the electrosurgical return electrode, (3) 

using electrosurgical return electrodes with the largest practical contact area, and 

(4) assuring proper application of the electrosurgical return electrode to the 

patient. 

WARNING Verify patient mode. Incorrect patient mode may result in inaccurate 

heart rates and inappropriate alarm settings. 

Even though the Propaq Encore contains fully isolated patient-connected circuitry, it has 

not been specially designed for direct cardiac application. 

The Propaq Encore can be used on patients with pacemakers. See “Using the Propaq 

Encore with pacemaker patients” on page 35.

Reference Guide Patient monitoring 31 

ECG connector and applicable accessories 

Use only with accessories provided or recommended by Welch Allyn. Refer to Products 

and Accessories. 

To prevent injury, use the provided garment clips to route the ECG cables away from the 

patient’s head. 

WARNING Use of ECG cables with loose or faulty detachable lead wires may 

cause erratic behavior of the ECG waveform, SpO 2 , C-Lock, and NIBP due to 

intermittent ECG lead wire connections. 

Preparation 

Caution To protect the Propaq Encore from damage during defibrillation, for 

accurate ECG information, and for protection against noise and other interference, 

use only ECG electrodes and cables (namely, ones with internal current-limiting 

resistors) specified or supplied by Welch Allyn, and follow recommended 

application procedures. 

WARNING Use only ECG safety cables that are designed so that they cannot 

accidently be plugged into an AC mains outlet or make contact with other 

hazardous electrical potentials including earth ground. To prevent damage during 

defibrillation, don’t use ECG cables without 1K series resistors. 

Preparing the monitor 

Preparing for ECG monitoring with the Propaq Encore requires you to prepare the monitor, 

prepare the patient, set up the ECG channel, and then set the ECG alarms. 

1. Inspect the ECG cable for wear, breakage, or fraying. Replace the cable if it shows 

signs of any of these. Plug the ECG cable into the ECG connector on the Propaq's left 

side panel. 

WARNING Before you use a Propaq on a new patient, always turn it off for a few 

seconds, then turn it on again. This clears the prior patient’s trend values, alarm 

limit settings, and NIBP cuff inflation target. 

Preparing the patient 

2. If the monitor is off, press the OFF/ON switch to turn it on. 

3. Select the patient mode appropriate for the patient (Neonatal, Pediatric, Adult). To 

change patient modes, see “Monitor setup” on page 20. 

1. Thoroughly clean the skin areas where the electrodes will be attached. Attach lead 

wires to the electrodes before applying them to the patient. 

2. If you are using pre-gelled electrodes, use only electrodes that have not expired. 

Make sure there is a generous amount of gel in the electrode and that it has not dried. 

For best results, use silver/silver chloride electrodes. 

3. If you are using non-gelled electrodes, apply a 1 / 4 to 1 / 2 inch mound of gel over the 

electrode contact area.


Note 

Some electrodes may be subject to large offset potentials due to polarization. 

This effect is most likely when dissimilar metals are used for different electrodes, 

and may be severe enough to prevent obtaining an ECG trace. Furthermore, 

recovery time after application of defibrillator pulses may be compromised when 

using electrodes of dissimilar metals. Squeeze bulb electrodes, even if all of the 

same metal, are particularly vulnerable to this effect. Stainless steel needle 

electrodes are prone to having large erratic offset drifts, and are not 

recommended.

5. Support the ECG cable so it does not stress the electrode wires, ECG cable 

connectors, or electrodes. 

Note 

Two RESP leads are available. Choose the one that gives you the best signal. If 

neither signal is adequate, it may be necessary to experiment with nonstandard 

electrode placement such as placing the RA and LA electrodes on the respective 

mid-axillary lines just above the level of the nipples. 

6. If an electrosurgical unit is going to be used, place the ECG cable and electrode wires 

as far as possible from the surgical site and from the electrosurgical return electrode 

and its cables. This will minimize interference. 

By now there should be some kind of ECG waveform displayed on the monitor. A 

heart rate should be displayed to the right of the waveform. Depending on how the 

Propaq Encore is programmed, a beep tone may occur with each detected QRS 

event.


7. If there is no waveform, check the electrodes, wires, cable, and the monitor for a 

possible lead fault. 

If an ECG electrode becomes disconnected or disrupted so that the Propaq Encore 

cannot receive the ECG signal, a message and tone are conveyed with an equipment 

alert. 

Setting up the ECG/RESP channel 

Setting ECG/RESP alarms 

Press ECG or ECG/RESP (available with the Impedance Pneumography Option) to set the 

selections: ECG SIZE, ECG LEAD, RESP SZE (available with Impedance Pneumography). 

The MORE button displays the second ECG/RESP menu and a status window with 

selections for HR/PR TONE, PACER DISPLAY, ECG BANDWIDTH, and RESP LEAD 

(available with Impedance Pneumography). If the patient being monitored has a 

pacemaker, you may want to turn on the Pacer indicator function. 

Set the alarm limits according to your hospital's standards. 

Motion artifact or other factors can cause false HR/PR alarms. To help minimize false 

alarms, the Propaq delays or “holds off” triggering an HR/PR alarm for 3 seconds. During 

this holdoff period, if the Propaq detects that the patient’s HR/PR vital sign has returned to 

acceptable limits, the Propaq cancels the alarm holdoff. The next time an HR/PR limit is 

violated, the Propaq starts a new 3-second HR/PR alarm holdoff period. 

How ECG/RESP is displayed 

Patient artifact 

Because of the critical nature of monitoring ECG, it is always displayed in the top part of 

the waveform display area. The ECG waveform is the only waveform that cannot be 

turned off using the Setup Wave Select Menu. 

Respiration rate numerics are sourced from the CO 2 channel and displayed as BR when 

CO 2 is active. Otherwise, respiration rate numerics are sourced from the ECG/RESP 

channel and displayed as RR. 

Patient movement and other artifact might cause the waveform to move on the display. 

Most artifact such as this is automatically detected, and the waveform is adjusted so that 

it always remains centered in the waveform window. 

Severe artifact and interference (such as interference from defibrillation) may cause the 

waveform to move off the display. The Propaq Encore will always automatically reposition 

the waveform in just a few seconds so you can see it again.

Note 

The Propaq Encore counts as “breaths” respiratory efforts that are larger than 

two times background Cardiovascular Artifact (CVA). 

Since RESP is derived from the same leads as the ECG channel, the Propaq 

Encore determines which signals are cardiovascular artifact and which signals are 

a result of respiratory effort. If the breath rate is within five percent of the heart 

rate or a multiple or sub-multiple of the heart rate, the monitor may ignore breaths 

and trigger an apnea alarm. 

Using the Propaq Encore with pacemaker patients 

Pacemaker signals 

Pacer display 

WARNING Pacemaker signals can differ from one pacemaker to the next. The 

Association for Advancement of Medical Instrumentation (AAMI) cautions that “in 

some devices, rate meters may continue to count the pacemaker rate during 

occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon rate 

meter alarms. All pacemaker patients should be kept under close or constant 

observation.” 

If the patient being monitored has a pacemaker, the Propaq Encore detects and can 

indicate the occurrence of pacemaker signals. With the Propaq, pacemaker signals are 

not counted as heart beats as long as the pacemaker signal meets the pulse amplitude, 

pulse width, and overshoot/undershoot specifications listed in Appendix B. 

On the Propaq Encore display, vertical dashed lines indicate each time a pacemaker signal 

is detected when the Propaq Encore PACER function is turned on. The waveform “spike” 

produced by the pacemaker will also be displayed if it contains sufficient energy. Whether 

the pacer is atrial, ventricular, or both, the indicator and the spike appear. If the PACER 

function is turned off, only the pacemaker spike is displayed:

Turn the pacemaker indicator on and off 

Noise on the signal 

The status of the pacer display is shown in the ECG status window. Turn PACER DISPLAY 

on or off using the NEXT and CHANGE buttons. 

Noise on the ECG signal may be detected as pacer signals, causing the pacer indicator to 

appear on the display. If you don't need to indicate pacemaker signals, you may want to 

turn off the pacemaker indicator for a better display of the ECG waveform. 

WARNING The presence of much pacer-like noise can cause the displayed heart 

rate to be erratic even though the ECG trace may look clean with the pacer 

indicator off. Fix the noise problem by using fresh ECG electrodes and an ECG 

cable whose lead wires make good connections.


Using the filter to better display a waveform 

The Propaq Encore includes a filter that reduces noise from the ac power signal and 

produces a much clearer ECG waveform. To set the filter, press SETUP, MORE, MORE, 

SERVICE, YES (to access the Service Menu), MORE, MORE, SETTINGS to display the 

Settings Menu. Select the FILTER function with the NEXT button and press the CHANGE 

button to change settings. 

Set the filter to the ac mains frequency of your hospital (either 60 or 50 Hz). 

Simultaneous equipment alerts 

MULTIPLE. If multiple equipment alerts occur simultaneously, the Propaq monitor 

displays this message. In this situation, the source of the alert may not be displayed 

(resulting in the message MULTIPLE). Look for blank numeric or waveform areas on 

the display, or status messages at the top of the display to identify the source(s) of 

multiple alerts. 

Note 

The monitor can also display MULTIPLE LEAD FAIL if, for example, there is a 

problem with an ECG lead and RESP lead at the same time. In this case, the 

monitor will alternately display ECG FAULT and RESP FAULT. Check all ECG and 

RESP leads for proper connection and operation. 

ECG messages 

RESP messages 

ECG FAULT. (This message is displayed in the status message area at the top of the 

display.) A problem occurred with ECG. If the problem is caused by a defective or 

disconnected lead, the monitor typically displays an additional message that indicates 

which lead failed (such as LL LEAD FAILED). Check the ECG lead for proper 

connection and operation. 

ECG LEAD CHANGED. The Propaq monitor has automatically changed an ECG lead 

due to a lead wire or electrode problem. 

LEAD FAIL: REPLACE ELECTRODES. The cable may not be properly connected to 

the electrodes or the electrodes may have failed. Check for proper connection; 

replace electrodes if needed. 

MULTIPLE LEAD FAIL. The monitor displays this message if multiple ECG leads fail. 

Check all ECG leads for proper connection and operation. 

RESP FAULT. (This message is displayed in the status message area at the top of the 

display.) A problem occurred with RESP. The monitor typically displays an additional 

message indicating the cause of the problem, such as a problem with a RESP lead. 

Check for proper connection; replace electrodes if needed. 

LEAD FAIL. One or more electrodes are making very poor or no contact. Check for 

proper connection; replace electrodes if needed. 

INAPPROPRIATE ECG CABLE. ECG cable appears not to contain 1 kW current 

limiting resistors. These resistors are required for RESP operation and to protect the 

monitor from damage during defibrillation. Replace cable with proper type.

Intended use 

NOISY SIGNAL, CHECK ELECTRODES. Electrodes are making poor contact and

WARNING If a disconnected lead is in too close proximity to other electrical 

devices, it may cause false heart rate, a failure to detect apnea, or a failure to 

display a Lead Fail message. 

This section applies only to Propaq Encore Models 204EL and 206EL. If you don't have 

one of these models, you can skip this section. 

The Propaq Encore invasive pressure channel is intended for measuring arterial, venous, 

and intracranial pressures using invasive transducers with 5 μV/V/mmHg sensitivity. The 

Propaq Encore can be used with many types of transducers, including nondisposable, 

disposable dome, and fully disposable. 

Invasive pressure connectors and transducers 

Recommended transducers for use with the Propaq Encore are listed in Products and 

Accessories. Do not use light-sensitive disposable transducers. Transducers must be 

used according to your hospital's standards and the manufacturer's recommendations. 

Always refer to the manufacturer's Directions for Use before using the transducer. 

WARNING If electrocautery is used, always avoid using any transducer with a 

conductive (metal) case that is electrically connected to its cable shield. Using a 

conductive transducer case with such a shield connection risks high-frequency 

burns at the ECG electrodes if the transducer case becomes earth grounded. 

WARNING Although complete disconnections of invasive pressure transducers 

will be detected by the normal alarm functions, partial disconnection will not be 

detected, nor will the use of some incompatible transducers. The user must 

exercise reasonable measures to ensure that approved transducers are used and 

that pressure transducers are connected properly.

Preparation 

Preparing the transducer 

Zeroing the transducer 

Preparing for invasive pressure monitoring with the Propaq Encore requires you to 

prepare the transducer, zero the transducer, set up the pressure channel, and set the 

invasive pressure alarm limits. 

1. Inspect the transducer cable for wear, breakage, or fraying. Replace it if the cable 

shows signs of any of these. Replace the transducer dome if necessary. 

2. Apply the transducer according to your hospital's procedures. Always refer to the 

transducer manufacturer’s Directions for Use. 

3. If the transducer is a disposable unit with separate cable, connect the transducer to 

the transducer cable. Plug the transducer cable into an invasive pressure connector 

on the left side panel.

Setting the invasive pressure alarms 


Rezeroing a transducer 

You can rezero a transducer at any time, after again opening the transducer stopcock to 

atmospheric air. If the transducer has already produced pressure readings, rezeroing 

provides a new zero reference for the Propaq. 

If the zero value is not accepted, the Propaq Encore continues to use the previous zero 

reference and displays the pressure values and waveforms based on that value. If the 

new zero value is accepted, the new pressure values based on the new zero value are 

displayed, and the waveform is adjusted according to the new scale. 

WARNING If a ZERO button is pressed after an invasive pressure channel has 

been successfully zeroed and is currently monitoring a pressure waveform, the 

message ZERO REJECTED will display in the invasive pressure numerics 

window. This message will preempt the valid invasive pressure numerics until the 

CANCEL button in the Invasive Pressure Menu is pressed. 

WARNING If the invasive pressure channel enters an alarm condition while the 

ZERO REJECTED message is overriding the invasive pressure numerics, no 

invasive pressure numerics will flash to indicate invasive pressure is in alarm. 

To remove the ZERO REJECTED message and to restore the invasive pressure numerics 

during an invasive pressure alarm, you must return to the invasive pressure menu and 

press CANCEL. This will restore the invasive pressure numerics. 

How invasive pressure is displayed 

From the invasive pressure signal, the Propaq Encore displays both a pressure waveform 

and pressure numeric values (systolic, diastolic, and mean). The waveform is displayed in 

a waveform window (if the waveform is turned on in the wave select window). The 

numerics are displayed in the blood pressure numerics windows. 

The Propaq Encore allows you to identify the pressure measurement with a selectable 

label, and the numerics can be displayed in different formats. 

The pressure waveform scales are not displayed until you zero the transducer. Once the 

zero reference has been established the scales automatically appear.

Invasive pressure messages 

The following messages can appear in the numerics window. 

NOT ZEROED (or NO ZERO). No zero reference has been established. The monitor 

displays the pressure waveform, but to protect against erroneous readings, the 

pressure waveform scale is not displayed. To remove this message, zero the 

transducer. 

ZEROING. This message briefly appears as the transducer is being zeroed. 

ZEROED. This message appears after the zero value has been accepted. It remains 

for eight seconds and is replaced by the current pressure values. 

ZERO REJECTED (or REJECT). Unable to establish a zero reference value. The 

message remains until the CANCEL button is pressed. 

CANCELED. This message appears if CANCEL is pressed while the channel is 

zeroing. 

These equipment messages can appear in an equipment alert window. 

TRANSDUCER NOT DETECTED. The transducer connection is broken. 

TRANSDUCER SHORT CIRCUIT. This message appears when the Propaq Encore 

senses a short in the transducer. The transducer should be replaced. 

INCOMPATIBLE TRANSDUCER. Check the compatible transducers listed in Products 

and Accessories to ensure you are using a compatible transducer.


NIBP 

Intended use 

The Propaq Encore noninvasive blood pressure channel (NIBP) indirectly measures arterial 

pressures using an inflatable cuff. If ECG is also monitored, the Propaq Encore 

synchronizes the NIBP measurement process to the occurrences of the R-wave, 

increasing accuracy in cases of extreme artifact, diminished pulses, or some 

dysrhythmias. 

WARNING The patient's limb should be periodically observed to ensure that the 

circulation is not impaired for a prolonged period of time. 

WARNING The Propaq Encore should never be used to monitor NIBP on one 

patient while simultaneously monitoring ECG on another patient. 

WARNING If a noninvasive blood pressure measurement is suspect, repeat the 

measurement. If you are still uncertain about the reading, use another method. 

WARNING Do not attempt to take NIBP pressures on patients during 

cardiopulmonary bypass. 

WARNING Some or all NIBP safety functions are disabled in the NIBP TEST 

screen in the Service Menu. Do not attempt to conduct NIBP TEST when the cuff 

is attached to a patient. 

The Propaq Encore NIBP channel has been calibrated to agree with a central invasive 

blood pressure. Diastolic pressures may be 5 to 10 mmHg lower than the auscultatory 

equivalent. Systolic pressures may be lower than radial invasive equivalent. 

Neonatal Mode is intended for use on infants of up to about 44 weeks gestational age in 

neonatal care settings. The Neonatal Mode provides the lowest cuff pressure and 

shortest inflation time limits to ensure patient safety and comfort. 

Pediatric Mode is intended to be used on larger infants and small children up to nine 

years old in pediatric care settings. This mode supports the widest range of cuff sizes and 

a higher range of patient numerics for the hypertensive infant or child while still restricting 

the cuff pressure and inflation times to limits lower than those allowed for adults. 

Adult Mode provides the full range of patient numerics and cuff pressures but limits the 

cuff sizes available to the standard child cuff and larger. 

NIBP measurements are affected by normal physiological pressure variations from 

reading to reading. Normal respiration may affect pressure by as much as 10 to 20 mmHg. 

Patient’s emotional state, body position, and cuff fit may also adversely affect NIBP 

measurements. In some individuals, the act of taking blood pressure readings may alter 

the blood pressure. Successive readings on the same patient may vary for the above 

reasons. 

The static accuracy of the Propaq’s internal manometer can be verified by a qualified 

biomedical engineer using a mercury column manometer (refer to the Propaq Encore 

Service Manual). The accuracy of the Propaq’s determination of systolic, diastolic, and 

mean pressures in a clinical setting can only be assessed by careful statistical analysis of 

controlled clinical trials of representative patient populations.


Improve NIBP accuracy with Smartcuf ® 

NIBP measurements can be adversely affected by many factor such as cardiac 

arrhythmias, sudden changes in blood pressure, body motions such as convulsions or 

shivering, bumping the cuff, vibration, vehicle motion, or weak pulses. 

The patented Smartcuf software filtering technology greatly increases NIBP 

measurement accuracy in the presence of motion artifact or diminished pulses. Smartcuf 

synchronizes the NIBP reading with the R-wave of the patient’s ECG to eliminate noise 

created by external stimuli such as patient motion or vibration. The monitor must perform 

ECG monitoring while using Smartcuf. 

To enable the Smartcuf filter: 

• Connect the ECG leads to the patient and perform ECG monitoring during NIBP. 

• From the Main Menu, press NIBP to display the NIBP Menu and set Smartcuf to 

ON.

There may be some situations where it is desirable to disable Smartcuf. This may include 

situations with very extreme motion artifact, certain types of arrhythmias, or other 

situations where it is not possible to obtain a good ECG signal. NIBP measurements can 

still be performed when Smartcuf is disabled. 

To disable Smartcuf, from the Main Menu press NIBP to display the NIBP Menu and set 

Smartcuf to OFF.


NIBP connector and cuffs 

Use Propaqs with approved hoses and cuffs listed in Products and Accessories. The 

Propaq Encore uses a single-hose cuff. Cuffs that conform to AAMI or AHA guidelines 

should be used. Select the proper size of cuff based on the limb circumference.

circumference of the limb is too large for the cuff. In that case, use the Pediatric 

Mode. In the Pediatric Mode, the maximum cuff inflation pressure can exceed 

150 mmHg, and two retries are allowed. 

Preparation 

For information about patient mode specifications, see “NIBP” on page 104. 

Setting up for noninvasive blood pressure monitoring requires three steps: place the cuff 

on the patient and connect the cuff to the monitor, set up the NIBP channel, and set the 

NIBP alarm limits. 


seconds, then turn it on again. This clears the prior patient’s NIBP cuff inflation 

target, trend values, and alarm limit settings. 

At powerup, the Propaq has an NIBP default inflation pressure (cuff inflation target) based 

on the patient mode (see “NIBP” on page 104 for the values). After each NIBP 

measurement, the Propaq adjusts the target inflation pressure to optimize the next NIBP 

measurement. To avoid possible patient discomfort, be sure to turn the monitor off and 

then on between different patients to reset the cuff inflation target to the default value. 

Place and connect the cuff 

1. Squeeze as much air from the cuff as you can before placing it on the patient.


Cuff applied evenly and 

snugly with bottom edge of 

cuff one inch above 

antecubital fossa 

Possible cuff 

placements for 

neonates 

2. Place the cuff on the limb. 

When you place the cuff, it should ideally be placed at the same level as the heart. If 

above the heart, add 1.9 mmHg to the NIBP measurement for every inch the cuff is 

above the heart. If below the heart, subtract 1.9 mmHg for every inch. 

The cuff should fit snugly, but not be uncomfortable. The hose must not be kinked or 

pinched. 

Ensure that the cuff tubing is centered over the brachial artery. 

Note 

A cuff that is not properly connected to the patient may result in a false reading if 

the patient and cuff are moved by motion artifact or clinical personnel during the 

NIBP measurement. Always verify the cuff is properly placed on the patient. 

Set up the NIBP channel 

3. Screw the hose connector onto the NIBP connector on the monitor's left side. 

4. If motion artifact such as shivering, coughing, or vehicle motion interferes with NIBP 

readings, do the following: 

Position the patient’s limb away from the body so the applied cuff is not in contact 

with the patient’s body or any other object such as a bed rail. Try to keep the cuff at 

the same level as the heart. 

Connect the ECG leads to the patient and perform ECG monitoring during NIBP. 

Press the NIBP button to display the status window and menu.

Important information about automatic measurements 

NIBP messages 

A blood pressure measurement will begin when the minute of the time of day clock is 

evenly divisible by the interval. For example, if the interval is set to 10 (minutes), 

measurements will begin at the hour and at 10, 20, 30, 40, and 50 minutes past the hour. 

Note, however, that for intervals 1, 2, or 3 (minutes), measurements begin 1, 2, or 3 

minutes after the interval is set. For example, if the 1 minute interval is selected at 

10:45:20, the next measurement starts at 10:46:20. 

The start time may be delayed if the previous measurement ended within 30 seconds of 

the scheduled start time, because the monitor requires that the cuff pressure be below 

5 mmHg for a minimum of 30 seconds between measurements to allow time to restore 

blood flow to the limb. 

The following NIBP messages can appear in the equipment alert window. An NIBP 

caution message also appears in the numerics window. If an error number (ERR# x) is 

listed in an NIBP trend printout or display, it indicates that the corresponding NIBP 

equipment alert occurred. 

AIR LEAK, CHECK HOSE (ERR# 1). The Propaq Encore could not properly inflate cuff. 

Check the hose and cuff for obvious leaks, such as O-rings in the hose connections. 

CUFF NOT DETECTED (ERR# 2). During cuff inflation the detected pressure did not 

sufficiently rise. Check that the cuff connection is tight and take the measurement 

again. 

KINKED HOSE, CHECK HOSE (ERR# 3). The Propaq Encore could not properly inflate 

cuff. Check for a kinked hose between the monitor and the patient. 

OVERPRESSURE CONDITION (ERR# 4). The pressure in the cuff exceeded the 

acceptable limits for patient mode. Check the hose and try taking another 

measurement. 

WEAK PULSES, CAN'T FIND SYS/DIA (ERR# 5). There are not enough pulses to 

determine the systolic or diastolic pressures, but a mean pressure is available. Try 

reapplying the cuff after squeezing as much air from it as you can. 

ARTIFACT, CAN’T FIND SYS/DIA (ERR# 6). The systolic or diastolic pressures are 

unreliable due to artifact, but a mean pressure is available. May be caused by patient 

motion. 

NO PULSES DETECTED (ERR# 7). The cuff may not be properly applied to the patient, 

or the patient may not have detectable pulses due to shock or arrhythmias. 

WARNING The Propaq Encore cannot differentiate between physiologic and cuff 

application causes of the NO PULSES DETECTED message. Always evaluate the 

patient for presence of life threatening conditions whenever this message occurs. 

CONNECT ECG TO REDUCE NIBP ARTIFACT (ERR# 8). NIBP artifact prevents a valid 

reading. Connect ECG electrodes to improve NIBP measurements. 

NO VALID BLOOD PRESSURE FOUND (ERR# 9). This message can occur due to 

motion artifact, the Propaq Encore being set in the wrong patient mode, or the wrong 

hose or cuff being used in relation to the patient mode.


CALIBRATING, PLEASE WAIT (ERR# 10). The Propaq Encore periodically recalibrates 

the NIBP channel to ensure it can properly make NIBP determinations. Normal 

monitor operation continues while the NIBP channel is calibrating. If the NIBP channel 

has not updated its calibration in 15 minutes, the channel will briefly deactivate until a 

new calibration has occurred. 

LOW BATTERY, NIBP DISABLED (ERR# 11). The battery lacks sufficient voltage to be 

able to operate the NIBP channel. Connect the Encore to the ac power adapter. 

SERVICE REQUIRED, NIBP DISABLED (ERR# 12). Have the monitor serviced. 

CUFF TOO LARGE FOR PATIENT MODE (ERR# 13). The monitor detects a cuff too 

large for the current patient mode. First, verify the patient mode. If the patient mode 

is correct, make sure the cuff fits snugly. If this alert occurs in Neonatal Mode, change 

the patient mode to Pediatric Mode and check alarm limits. If the alert occurs in 

Pediatric Mode, change to Adult Mode and check the alarm limits. Note that different 

pressures and retries are used for each mode as stated in “NIBP” on page 104. 

KINKED OR NEONATE HOSE (ERR# 14). This message occurs when the neonate 

hose is detected in adult patient mode. Change the hose or the patient mode 

selection. 

ARTIFACT PRESENT, MINIMIZE ARTIFACT (ERR# 15). The monitor has detected too 

much artifact to allow accurate readings. Take steps to reduce artifact. Position the 

patient’s limb away from the body so the applied cuff is not in contact with the 

patient’s body or any other object such as a bed rail. If the Smartcuf motion artifact 

filter is on, make sure that the ECG leads are properly connected to perform ECG 

monitoring during NIBP. If the Smartcuf motion artifact filter is off, consider turning it 

on (and connect ECG if not already connected).

Pulse oximetry (SpO 2 ) 

WARNING Oxygen saturation measurements using pulse oximetry are highly 

dependent on proper placement of the sensor and patient conditions. Patient 

conditions such as shivering and smoke inhalation may result in erroneous oxygen 

saturation readings. If pulse oximetry measurements are suspect, verify the 

reading using another clinically accepted measurement method, such as arterial 

blood gas measurements on a co-oximeter. 

WARNING Tissue damage can be caused by incorrect application or use of a 

sensor (e.g., wrapping the sensor too tightly, applying supplemental tape, failing 

to periodically inspect the sensor site, leaving a sensor on too long in one place). 

Refer to the Directions for Use provided with each sensor for specific instructions 

on application and use, and for description, warnings, cautions, and 

specifications. 

WARNING Sensors exposed to ambient light while not applied to a patient can 

exhibit semi-normal saturation readings. Be sure the sensor is securely placed on 

the patient and check its application often to ensure accurate readings. 

WARNING Inaccurate measurements may be caused by venous pulsations. 

WARNING The pulse oximetry option can be used during defibrillation, but the 

readings may be inaccurate for a short time. 

WARNING A very sudden and substantial change in pulse rate can result in 

erroneous pulse rate readings. Be sure to validate the patient data and patient 

condition before intervention or change in patient care. 

WARNING Interfering Substances: Carboxyhemoglobin may erroneously 

increase readings; the level of increase is approximately equal to the amount of 

carboxyhemoglobin present. Methemoglobin may also cause erroneous readings. 

Dyes, or any substances containing dyes, that change usual arterial pigmentation 

may cause erroneous readings. 

WARNING Before you use a Propaq monitor on a new patient, always turn off 

the monitor for a few seconds, then turn it on again. This clears the prior patient’s 

trend values, alarm limit settings, and NIBP cuff inflation target. 

Each SpO 2 sensor is designed for application to a specific site on the patient within a 

certain size range. To obtain optimal performance, use an appropriate sensor and apply it 

as described in the sensor’s directions for use. 

If excessive ambient light is present, cover the sensor site with opaque material to block 

the light. Failure to do so may result in inaccurate measurements. Light sources that can 

affect performance include surgical lights (especially those with a xenon light source), 

bilirubin lamps, fluorescent lights, infrared heating lamps, and direct sunlight. 

If NIBP will be monitored while using SpO 2 , place the NIBP cuff on a different limb than 

the SpO 2 sensor to help reduce unnecessary SpO 2 alarms. For optimal measurements, 

avoid placing the SpO 2 sensor on the same limb as an arterial catheter or intravascular 

line. 

Loss of pulse signal can occur if the sensor is too tight, there is excessive ambient light, 

an NIBP cuff is inflated on the same limb as the sensor, there is arterial occlusion proximal 

to the sensor, the patient is in cardiac arrest or shock, or the patient has hypotension, 

severe vasoconstriction, severe anemia, or hypothermia.


Perform SpO 2 monitoring with Masimo option 

1. Attach the sensor to the patient according to the sensor manufacturer's instructions, 

observing all warnings and cautions. 

WARNING Use only Masimo accessories and sensors with the monitor with 

Masimo SpO 2 option as listed in Products and Accessories (810-0409-XX). 

2. Inspect the Masimo SpO 2 cable. Replace it if it shows any signs of wear, breakage, or 

fraying. Plug the sensor into the cable and plug the cable into the Propaq monitor. 

Note 

The monitor displays STANDBY in the SpO 2 numeric window until it measures 

and displays the SpO 2 value. 

As oxygen saturation increases and decreases, the pitch of the heart tone rises 

and falls. 

The monitor self-calibrates the SpO 2 channel whenever the monitor is first turned 

on or a sensor is first connected to the SpO 2 channel. 

3. From the Main Menu, press SpO2 (or SpO2/CO2, then SpO2) to display the SpO 2

5. Adjust the placement of the sensor until a good SpO 2 waveform is displayed. A 

waveform with artifact may cause erroneous oxygen saturation readings. 

6. Set alarm limits according to your hospital’s standards. 

Note 

To help minimize false alarms, the Propaq monitor briefly delays or "holds off" 

triggering both audible and visual alarms for limit violations for SpO 2 % and Pulse 

Rate for 10 seconds. After the alarm hold-off period begins, if the monitor detects 

that the patient’s vital sign has returned to acceptable limits, the monitor cancels 

the alarm hold-off. The next time a vital sign limit is violated, the monitor starts a 

new hold-off period. 

The “averaging time” for SpO 2 measurements is fixed at eight seconds. 

7. If patient movement interferes with measurements, consider the following possible 

solutions: 

• be sure the sensor is secure and properly applied 

• use a new sensor with fresh adhesive backing 

• select a different type of sensor 

• move the sensor to a less active site


Perform SpO 2 monitoring with Nellcor option 

1. Attach the sensor to the patient according to the sensor manufacturer's instructions, 

observing all warnings and cautions. 

WARNING Use only Nellcor accessories and sensors with the monitor with 

Nellcor SpO 2 option as listed in Products and Accessories (810-0409-XX). 

2. When using a sensor extension cable, inspect the cable before use. Replace it if it 

shows any signs of wear, breakage, or fraying. Plug the sensor into the cable and plug 

the cable into the Propaq monitor, or plug the sensor directly into the monitor. 

3. If the monitor SpO 2 receptacle has a locking ring, lock the connector in place by 

turning the locking ring clockwise until it stops. For other connectors, make sure the 

plug is all the way in. 

Caution If you see the error message DEFECTIVE SpO2 SENSOR, either the 

sensor is not compatible with the monitor or the sensor is not working properly. 

Check Products and Accessories (810-0409-XX) to be sure the sensor is 

compatible. If compatibility is not a problem, try another sensor. 

Note 

The monitor displays STANDBY in the SpO 2 numeric window until it measures 

and displays the SpO 2 value. As oxygen saturation increases and decreases, the 

pitch of the heart tone rises and falls. 

The Nellcor SpO 2 option periodically performs an internal adjustment which 

causes the SpO 2 waveform to appear flat for a brief period. 

4. From the Main Menu, press SpO2 (or SpO2/CO2, then SpO2) to display the first

Indications for Use 

Use when patient movement is minimal. 

Use when patients exhibiting movement are preventing accurate 

measurement at NORMAL setting. 

9. If the C-LOCK function is desired, press C-LOCK to set it to ON. 

Note 

C-LOCK synchronizes the pulse oximeter's systole determination to the R-wave 

to reduce the effects artifact may have on SpO 2 measurements. Under some 

conditions you may find more stable SpO 2 readings with C-LOCK set to ON. 

SYNC appears next to the waveform when synchronization to the ECG has been 

obtained. Synchronization takes a few seconds to establish the first time. If C- 

LOCK is on and the HR source is SpO 2 , the heart rate source is automatically 

changed to ECG. An ECG signal must be present or C-LOCK does not activate. 

If you get false SpO 2 alarms with patients with low perfusion states or multiple 

arrhythmias, try turning off C-LOCK. 

10. Set alarm limits according to your hospital’s standards. 

Note 

To help minimize false alarms, the Propaq monitor briefly delays or "holds off" 

triggering both audible and visual alarms for limit violations for SpO 2 % and Pulse

• be sure the sensor is secure and properly applied 

• use a new sensor with fresh adhesive backing 

• select a different type of sensor 

• move the sensor to a less active site


Perform SpO 2 “spot-cCheck” monitoring 

The SpO 2 Standby Mode allows you to remove the SpO 2 sensor from a patient without 

having to disable all alarms or disconnect the SpO 2 sensor cable from the Propaq monitor. 

You can therefore perform intermittent or “spot-check” SpO 2 monitoring. 

1. While monitoring SpO 2 , remove the SpO 2 sensor from the patient, but leave it 

connected to the monitor. When the monitor detects the lack of a pulsatile waveform, 

it sounds a patient alarm and displays this menu: 

SILENCE 

STANDBY 

2. Press STANDBY to place SpO 2 into the Standby Mode. 

Note 

The monitor suspends the SpO 2 alarm tone indefinitely and displays STANDBY in 

place of SpO 2 numerics. SpO 2 remains in the Standby Mode until the SpO 2 

sensor is reapplied to a patient. Other vital sign monitoring is not restricted. By 

contrast, if you press SILENCE instead of STANDBY, the monitor temporarily 

suspends all alarm tones; however, the alarm tone resumes after 90 seconds if 

the SpO 2 sensor is still disconnected from the patient. 

3. To resume SpO 2 monitoring, reapply the SpO 2 sensor to a patient. 

Note 

The monitor exits the Standby Mode and resumes SpO 2 monitoring 

The message STBY on the SpO 2 trend display and trend printouts indicates the 

monitor was in the SpO 2 Standby Mode. 

SpO 2 messages 

The following status message can appear in the equipment alert window or the SpO 2 

numeric display area: 

NO SENSOR DETECTED appears in the equipment alert window and indicates a 

probe has been disconnected from the monitor after being plugged in for more than a 

few seconds. 

SEARCH: during the search time, the SpO 2 channel tries to detect blood pulsing 

through the measurement site. Once the measurement has been established, the 

oxygen saturation value is displayed in the numeric window. 

STANDBY is displayed in the numeric window when the SpO 2 sensor is disconnected 

from the patient, an alarm occurs, and you press the STANDBY button. STANDBY is 

also displayed if you first plug the SpO 2 sensor cable into the monitor connector 

before attaching the SpO 2 sensor to the patient. 

DEFECTIVE SpO2 SENSOR. If you see the error message DEFECTIVE SpO2 

SENSOR, either the sensor is not compatible with the monitor or the sensor is not 

working properly. Check Products and Accessories (810-0409-XX) to be sure the 

sensor is compatible. If compatibility is not a problem, try another sensor.


Capnography (CO 2 ) 

Intended use 

The Propaq’s Capnography (CO 2 ) option is intended to noninvasively measure the 

following vital signs or events: End-tidal CO 2 (ETCO 2 ), Inspired CO 2 (INCO 2 ), Breath Rate, 

and Apnea. 

The CO 2 option is available as mainstream CO 2 , sidestream CO 2 , or Dualstream CO2 . 

Although Dualstream CO 2 provides both mainstream CO 2 and sidestream CO 2 

monitoring, only one method can be used at a time. The v option is required for any 

Propaq equipped with the CO 2 option. 

CO 2 reading accuracy is affected by the presence of interfering gases and vapors. If the 

CO 2 option is used on patients who are being administered oxygen (O 2 ) or nitrous oxide 

(N 2 O), be sure to set the appropriate compensation setting using the GAS COMP button. 



limit settings, and NIBP cuff inflation target. 

WARNING Avoid exposing a Propaq with the CO 2 option to non-patient sources 

of CO 2 such as vehicle engine exhaust or smoke. When such exposure is 

possible, avoid opening the printer door. Exposure to these CO 2 sources can 

temporarily trap v within the monitor or mainstream v sensor housing, even when 

monitor power is off. This can temporarily cause an erroneous elevated CO 2 

measurement baseline until the trapped CO 2 leaks out and the baseline returns to 

zero (which can require as long as 3-24 hours). 

Caution The mainstream CO 2 and sidestream CO 2 options are not 

recommended for use during magnetic resonance imaging (MRI) procedures. 

The magnetic fields involved will permanently damage the CO 2 sensor. 

Note 

CO 2 monitoring outside the specified operating temperature range can cause 

inaccurate CO 2 readings. The operating temperature range for the CO 2 option is 

different than the range of 0° to 40° C for other Propaq Encore functions: 

• Mainstream CO 2 operating temperature: 10° to 40° C 

• Sidestream CO 2 operating temperature: 5° to 40° C 

Mainstream CO 2 option 

The mainstream CO 2 option measures the carbon dioxide content of a patient’s inhaled 

and exhaled breath. A mainstream sensor is attached to an airway adapter in series with a 

ventilator’s patient breathing circuit. 

Patients using mainstream CO 2 must either be intubated or breathing through a wellfitting 

face mask connected to a breathing system such as an anesthesia circle system.


Sidestream CO 2 option 

The sidestream CO 2 option measures the carbon dioxide content of a patient’s inhaled 

and exhaled breath. A sidestream sensor is located within the Propaq monitor. The 

patient’s expired gas is aspirated from the airway and sent through a sampling line and 

sidestream watertrap to the internal sensor. 

Patients using sidestream CO 2 can either be intubated or non-intubated using a CO 2 

Sampling cannula or a combination CO 2 Sampling/Oxygen Delivery nasal cannula. 

CO 2 measurements and display 

The measured CO 2 levels are normally displayed as a waveform and an ETCO 2 numeric 

value. (The CO 2 waveform can be viewed when it is selected for display and the higherpriority 

IBP waveforms are not displayed.) If the INCO 2 numeric value is at an alarm level 

greater than 7.5 mmHg (or 1 kPa or 1%), it is also displayed. 

If mainstream CO 2 is active, the Propaq displays MCO2. If sidestream CO 2 is active, the 

Propaq displays SCO2. The Propaq displays CO2 if either or both the mainstream sensor 

and sidestream watertrap are installed in the Propaq but neither are active.

SETUP 

Displayed values of ETCO 2 and INCO 2 are the highest and lowest values (respectively) of 

CO 2 measured during the time interval set by the RESPONSE setting on the CO 2 Menu. 

You can set upper and lower alarm limits for ETCO 2 , and an upper alarm limit for INCO 2 . 

The monitor only displays the numeric value for inspired CO 2 (INCO2) if it is in alarm or if it 

is greater than or equal to 7.5 mmHg (or ≥1 kPa or 1%). Refer to the CO 2 specifications in 

the Propaq Encore Reference Guide for more information. 

Breath rate measurements 

Breath Rate (BR) is determined from the CO 2 sensor. The Propaq displays a numeric BR 

value next to the CO 2 values. You can set upper and lower alarm limits for BR.


Apnea events 

In the Adult and Pediatric Mode, you can set the apnea delay to 6, 10, 15, 20, 25, or 30 

seconds. In the Neonatal Mode, you can set the apnea delay to 6, 10, 15, or 20 seconds. 

The Propaq initiates an alarm in response to each apnea event longer than the apnea delay 

setting. 

When an apnea event is detected, the BR numeric automatically goes to 0 and an apnea 

alarm occurs. After the alarm ceases, the Propaq prints an Apnea Ticket if the Apnea 

Ticket setting in the Printer Setup window is set to ON. 

Numeric area status messages 

The following status messages can appear in the numeric display area: 

OFF indicates no CO 2 source is selected. 

SRCH indicates the MCO 2 or SCO 2 sensor is preparing for a measurement. 

UNCAL indicates the monitor has detected a problem such as a lack of calibration, an 

obstruction, or a low battery. 

WARM UP indicates mainstream CO 2 has been activated and is preparing for 

operation. This typically requires 30 seconds at room temperature. 

START UP indicates sidestream CO 2 has been activated and is preparing for 

operation. This typically requires 30 seconds at room temperature.

Mainstream CO 2 monitoring 

1. Select the appropriate airway adapter. 

Use only accessories provided or recommended in Products and Accessories. Always 

refer to the manufacturer's Directions for Use for instructions about operation, 

cleaning, and replacement. 

WARNING Do not attempt to verify operation of the CO 2 sensor by blowing 

through it directly. Always blow through an attached airway adapter. Otherwise, a 

small amount of CO 2 from your breath may enter the CO 2 sensor housing and 

cause a small shift in the measured CO 2 values. It may take 3-24 hours for the 

sensor to return to proper calibration. 

WARNING Do not clean and/or reuse a single-patient-use airway adapter. When 

a single-patient-use airway adapter becomes occluded, replace it. 

2. Connect the adapter, ventilator circuit, and CO 2 sensor according to the 

manufacturer’s instructions. 

Adult airway adapter 

Window 

Low dead space airway adapter 

Window 

WARNING Prior to using an airway adapter, always look through the window 

lumen and inspect the adapter for inadvertently lodged obstructions and for 

window integrity. 

WARNING If the sensor does not easily slide onto the adapter, do not attempt to 

force these components together. They fit together in only one way. Take care not 

to damage the glass windows. 

WARNING After attaching the sensor to the adapter, check the adapter again for 

proper placement of the sensor and for window integrity. 

WARNING When attaching the airway adapter, position the adapter so the 

sensor is on top to avoid fluid collection in the sensor airway slot. Any 

concentration of fluids here can cause inaccurate CO 2 readings. 

WARNING Always check to make sure there are no leaks in the breathing 

circuit. Check all of the connections. 

3. Plug in the CO 2 sensor cable to the mainstream CO 2 connector on the Propaq left 

side panel. 

4. Set up the CO 2 channel and alarms. Follow the steps described on page 62. 

WARNING When disconnecting the CO 2 sensor from the tracheal or 

endotracheal tube, check the sensor to determine how hot it is. If it is too hot for 

patient comfort, do not allow it to come into contact with the patient.


Note 

When disconnecting the airway adapter from the ventilator circuit, always detach 

the CO 2 sensor from the airway adapter before removing the airway adapter from 

the ventilator circuit. 

How to set up the CO 2 channel and alarm limits 

After you connect the mainstream CO 2 sensor or sidestream CO 2 watertrap adapter, 

follow these steps to set up the CO 2 channel and alarm limits. 

Note 

After you connect a mainstream CO 2 sensor or sidestream CO 2 watertrap 

adapter, the Propaq displays the waveform briefly without a value range. It 

displays WARM UP (for mainstream) or START UP (for sidestream) in the CO 2 

numerics window. After about 20 seconds, the Propaq displays the CO 2 

measurement and waveform range. 

1. Press SpO2/CO2, CO2 to display the first CO 2 Menu. 

2. Press RANGE until you see the desired waveform scale range on the Propaq screen. 

The range choices are shown below.

mmHg 0-100 0-60 (default 0-30 

setting) 

kPa 0-14 0-8 0-4 

% 0-14 0-8 0-4 

Note If an inspired value is displayed indicating patient rebreathing (non-zero INCO 2 ), 

check the patient breathing circuit for proper function. Verify the sensor calibration 

against room air. If the Propaq continues to display inspired values, return the 

sensor to Welch Allyn for service. 

3. Press mm/s to select either 3.13, 6.25 or 12.5 mm/sec. The default setting is 6.25 

mm/sec. This sweep speed also applies to RESP. 

4. Press MORE to view the CO 2 status window. 

5. If either O 2 or N 2 O is being administered to a patient, press GAS COMP to set the 

proper gas compensation as listed below. If no other gas is being administered, set 

GAS COMPENSATION to OFF. (OFF is the default setting.)

Note 

If the ETCO 2 value is displayed as + + +, verify calibration against a known 

reference gas. If the sensor calibration is not accurate, return it to Welch Allyn for 

service.


6. Press RESPONSE to select either NORMAL, SLOW, or FAST. 

The FAST setting is recommended where a sudden step change in ETCO 2 is of 

concern, such as that induced by an air embolus in certain neurosurgical procedures. 

A SLOW response will decrease ETCO 2 false alarms when breath morphology varies 

considerably from one breath to the next. 

The default setting is NORMAL.

7. Set alarm limits for ETCO 2 , INCO 2 , and Breath Rate. 

WARNING For patient safety, it is recommended that the Breath Rate alarm 

limits always be turned on and set appropriately. 

Motion artifact or other factors can cause false RR/BR alarms. To help minimize false 

alarms, the Propaq delays or “holds off” triggering a RR/BR alarm for 5 seconds. After 

this holdoff period begins, if the Propaq detects that the patient’s RR/BR vital sign has 

returned to acceptable limits, the Propaq cancels the alarm holdoff. The next time a 

RR/BR limit is violated, the Propaq starts a new 5-second RR/BR alarm holdoff period. 

8. Set the alarm limit for Apnea Delay—this is the maximum time allowed between two 

successive breaths before an Apnea alarm occurs. 

After the first breath has been detected, the Apnea alarm limit setting will be 

automatically turned on for as long as the CO 2 channel is active. The RR/BR and 

Apnea Alarm Limit window is shown below. STAT SET does not affect the Apnea

Sidestream CO 2 monitoring 

WARNING If the sidestream CO 2 option is connected to a ventilatory circuit, be 

sure to adjust appropriate ventilator or anesthesia system settings to compensate 

for the sampling flow volume (90 or 175 ml/min) that is aspirated from the 

ventilatory circuit by the sidestream CO 2 option. 

WARNING Do not use sidestream CO 2 if flammable anesthetic gases are in 

use. 

Setting up for sidestream CO 2 monitoring requires these major steps: 

1. Connect the watertrap. 

2. Set up the CO 2 channel and alarm limits. 

3. Connect to a non-intubated patient. 

OR 

4. Connect to an intubated patient.

Alarm holdoffs 

Propaq audio and visual alarm hold-offs 

Motion artifact or other factors can cause false vital sign alarms. To help minimize false 

alarms, the Propaq briefly delays or “holds off” triggering alarms for certain vital sign limit 

violations. 

After the alarm holdoff period begins, if the monitor detects that the patient’s vital sign 

has returned to acceptable limits, the Propaq cancels the alarm holdoff. The next time a 

vital sign limit is violated, the Propaq starts a new alarm holdoff period. The following table 

summarizes the alarm holdoff periods.

When the Propaq is connected to the Acuity Central Monitoring System, Acuity does not 

receive any alarm indication from the monitor until this holdoff period expires. 

Propaq audio alarm hold-off with Acuity 

When a Propaq Encore in Adult or Pediatric Mode is connected to an Acuity System, the 

audio alarms at the bedside Propaq can be delayed up to 4 minutes and 15 seconds. The 

delay time is selected in Acuity software at the time of Acuity installation. Visual alarm 

indications are not delayed. 

Note 

This audio alarm holdoff does not occur in the Neonatal mode.


Setting alarm limits 

Adjust limits with STAT SET 

When you want to quickly set all alarm limits, the Propaq Encore can calculate new alarm 

limits using the patient’s current values. Press the STAT SET button in the Alarms Menu 

(SETUP, ALARMS, STAT SET). The Propaq Encore activates all alarms and calculates the 

limits for all monitored vital signs, except apnea delay. The monitor performs a 

mathematical function (addition, subtraction, or multiplication) on the current value of the 

vital signs to arrive at the new limits. The formulas for these calculations are shown in the 

table.

a. New alarm limits calculated by STAT SET cannot be outside the allowable alarm limit range. If a new limit is calculated to be above 

or below the allowable alarm limit range, it defaults to the maximum or minimum alarm limit allowed for that vital sign.


WARNING If a patient’s vital sign value falls outside of the upper or lower alarm 

range limit, STAT SET turns off the alarm and the alarm limit except for the 

following: 

1. The lower alarm limits for SpO 2 and ETCO 2 are not turned off by STAT SET. 

2. If HR/PR ALARM LIMITS in the Settings window is set to CANNOT TURN 

OFF, STAT SET affects HR/PR alarm limits as follows: 

• For an overrange HR/PR patient value (displayed as +++), the upper alarm 

limit is set to the maximum alarm limit, and the lower alarm limit is 

unchanged. 

• For an underrange HR/PR patient value (displayed as - - -), the lower alarm 

limit is set to the minimum alarm limit and the upper alarm limit is unchanged. 

• For an indeterminate HR/PR patient value (displayed as ???), the alarm limits 

are unchanged. 

Power-up equipment alert: program fault, settings lost 

If a PROGRAM FAULT: SETTINGS LOST, TIME/DAY RESET equipment alert appears when 

you turn on the monitor, the monitor cannot recall the programmed custom settings and 

current time and date. This can occur if the battery is drained or after new software has 

been installed. 

If this occurs, the monitor provides a special sequence of display windows to help you 

regain use of your monitor as quickly as possible. Refer to “Power-up equipment alert: 

program fault, settings lost” on page 11 and perform the described steps. 

If you follow these steps and the equipment alert reappears at powerup, the monitor may 

need to be serviced and the battery replaced. Contact a qualified service person. 

Troubleshooting system error messages 

If the monitor detects a system error, it will display a message similar to the following: 

ERROR NUMBER: 1-123-4567 

REMOVE CUFF FROM PATIENT 

PLEASE NOTIFY YOUR LOCAL SERVICE 

REPRESENTATIVE OR WELCH ALLYN PROTOCOL, INC. 

This type of message indicates that the monitor detected an internal system problem 

which may require service for the monitor. If the monitor displays this message, 

disconnect the monitor from the patient. Write down the error number for the service 

department, and send the monitor to your facility’s biomedical engineering department. 

Note 

The message REMOVE CUFF FROM PATIENT as shown above does not imply 

that the detected error is related to NIBP. It is simply a reminder to disconnect the 

NIBP cuff from the patient if a cuff is connected.

Trends 

Every two minutes, the Propaq Encore collects the monitored vital sign numerics and 

stores them in its trend memory, which can save the last five hours of trend information. 

(See “NIBP Trends “on the next page for exceptions.) All this information can be printed 

and viewed as a trend print. 

The trend status window and menu 

There are five trends: NIBP, RESP, P1, P2, and TEMP. Except for NIBP, all vital signs are 

continuously monitored from the time monitoring begins to the time it ends. 

Each trend shows the time of the reading, the HR/PR measurements, the SpO 2 value (if 

configured), and other values. The three blood pressure trends show systolic, diastolic, 

and mean pressures, and all but the TEMP trend show respiration rate, if it’s available. 

Columns on the trend table show the word ‘OFF’ for the vital signs not being monitored.

How trends are accumulated 

For each of the four continuous trends, numerics are sampled every two minutes to a

continues but the older data is no longer stored. The readings are displayed in descending 

order, most recent first.

NIBP trends 

The following is programmable: which trend window comes up first. The NIBP trend 

window is the factory default. 

To clear trend data before connecting a new patient, the monitor power must be cycled. 

This will prevent the trend data of a previous patient from being attributed to the new 

patient. 

A maximum of 128 NIBP readings are collected (up to 8 hours). NIBP is not measured 

continuously like other vital sign parameters. The numerics on this trend are captured at 

the time of the NIBP reading.

The ECG waveform 

If you have an expansion module set up with your monitor, you can print any waveform by 

pressing either the SNAPSHOT or START/STOP button on the expansion module when 

the waveform is displayed on the monitor. You can also set the monitor to print 

automatically. 

The number of seconds of data shown on the printout depends on the print speed set in 

the Printer Setup window. 

Patient vital sign numerics are printed above the waveforms. 

ECG is printed on a grid with major divisions (dotted lines) every 5 mm and minor 

divisions (single dots) every 1 mm. The ECG waveform is always printed if ECG is 

monitored. 

The invasive-pressure waveforms 

Pressure waveforms are printed on a grid with major divisions (vertical dotted lines) every 

5 mm, and the pressure scale grids are printed horizontally. 

The SpO 2 plethysmograph 

The plethysmograph is printed without a horizontal grid. The size is printed on the 

printout. Although no vertical scale is displayed for the SpO 2 waveform, a size indicator is 

displayed to show the relative gain of the waveform.

80 Printing Welch Allyn Propaq Encore Vital Signs Monitor 

CO 2 and RESP waveforms 

CO 2 waveforms are printed on a grid with major divisions (vertical dotted lines) every 

5 mm, and the pressure scale grids are printed horizontally. The waveforms and numerics 

are labeled as MCO 2 for mainstream CO 2 and SCO 2 for sidestream CO 2 . If neither CO 2 

option is active, the label is simply CO2. 

On the SNAPSHOT command only, the CO 2 and RESP waveforms will be printed with 

different sweep speeds than the other waveforms. 

Printing NIBP measurements

Acuity Central Monitoring system 

Intended use 

WARNING Use of equipment, accessories, and parts not recommended or 

supplied by Welch Allyn could result in inaccurate patient information or damage 

to the system. 

WARNING When Acuity is inoperable, be sure to keep Acuity patients under 

close surveillance, especially those prone to arrhythmias. Use Acuity only in 

conjunction with close surveillance by trained clinicians. 

WARNING Connect the Propaq Encore to an Acuity system only. Connecting to 

other networks could damage the monitor or injure the patient. If in doubt about 

the network jacks or devices, consult your facility’s Biomedical Engineering 

Department. 

WARNING Make sure the Acuity network cable is not damaged. The Acuity 

network cable is the sole link between the Propaq Encore and the Acuity Central 

Monitor. 

The Acuity system is used as a central monitoring system for Propaq Encore monitors 

configured to interface with Acuity. 

The Acuity system may be used to monitor all patients. For neonatal patients, use all 

Acuity features except the Welch Allyn Cordless Acuity and the arrhythmia detection 

option. The Acuity system is intended to be used in compliance with the instructions in 

this Propaq Encore Reference Guide, the Acuity System Reference Guide, and accepted 

hospital and clinical protocols. 

Connecting to the Acuity system 

1. If the Propaq Encore has already been connected to the patient, save the patient’s 

Trends and Alarm Limit settings by keeping the monitor turned on. (The Propaq 

Encore transmits up to five hours of trend information when you connect it to the 

Acuity network.) 

If the Propaq Encore has not been connected to the patient, clear any prior patient’s 

trends and alarm limit settings by turning off the Propaq Encore and after a few 

seconds, turning it on again. 

2. If the Propaq Encore is not already connected to the patient, attach leads and sensors 

to the patient as described in Chapter 2 of this reference guide.

4. Connect the AC adapter to the Propaq Encore and the wall outlet to charge the 

battery. Check to see that the battery charging light on the monitor’s right side panel 

is on. 

5. Confirm the patient identification at the bedside or enter the patient information at the 

Acuity Central Monitor using the Patient ID Setup Window. 

6. If alarm limits have not been set, do so at the Propaq Encore or at the Acuity Central 

Monitor using the Alarms Setup Window. 

WARNING If you don’t set alarm limits, Acuity uses preset settings (for 

arrhythmia limits), and the powerup default settings for the Propaq Encore. 

Note 

When a Propaq Encore in Adult or Pediatric Mode is connected to an Acuity 

System, the audio alarms at the bedside Propaq can be delayed up to 4 minutes 

and 15 seconds. The delay time is selected in Acuity software at the time of 

Acuity installation. Visual alarm indications are not delayed.

Power sources 

For in-hospital operation and recharging from ac mains, an ac power adapter plugs into the 

monitor. Use only a Welch Allyn ac power adapter to ensure protection against risk 

(leakage) current hazards. 

The Propaq Encore can also be powered and recharged from a dc source (isolated from ac 

mains) capable of supplying 12-28 Vdc and continuously supplying 25W. 

Caution When a transport vehicle’s battery system is used to provide input 

power to the Propaq Encore, surges caused by a defect in the vehicle’s power 

system may blow a fuse in the Propaq’s side panel or cause further damage to 

the Propaq. 

Power adapter intended use 

Welch Allyn power adapters are intended to be used only with Propaq monitors, and 

Propaq Encore monitors are intended to be recharged using only a Welch Allyn power 

adapter with a mating plug, and rated for your ac mains. 

The power adapter contains symbols on its labeling. For definitions of these symbols, see 

“Symbols” on page 3. 

WARNING Place the power adapter where it cannot fall and harm someone. 

Caution Use of other than Welch Allyn power adapters with the plug rated for 

your ac mains can damage or compromise the safety of the Propaq Encore 

monitor and may require fuse replacement in the power adapter. Verify that the 

Power Adapter is set for the proper mains voltage prior to plugging it into the 


Caution Do not autoclave the power adapter. Do not operate the power adapter 

with a damaged case, mains power cord, or plug. 

Verifying proper power-adapter configuration 

Prior to using the power adapter, check it for proper voltage selection by looking in the 

small indicator window on the front end (by the power switch). If the number in the 

window does not match your ac mains source voltage (100-120V or 200-240V), the 

adapter should be reconfigured. See the illustration on page 91. 

Your biomedical technician can change the voltage setting and fuses on the power adapter 

and can verify that your facility is using the correct power cord.

Replacing the power-adapter fuses 

The Power Adapter contains two fuses that can easily be replaced by service personnel if 

necessary. The adapter can contain spare fuses. 

Caution Replace each fuse only with the specified type. 

Procedure 

1. Unplug the power adapter’s removable cord from the ac mains outlet and the power 

adapter. 

2. Turn the power adapter so you can see the window that indicates the voltage setting. 

3. Using a small, flat-blade screwdriver, carefully pry the fuse module from the power 

adapter. 

4. Replace both fuses with the specified type. 

Note 

Both fuses should be replaced at the same time, even if only one fuse has 

opened due to an overcurrent situation. The unopened fuse may have been 

stressed and could become unreliable. 

Caution Spare fuses are contained in housings next to the fuses in the fuse 

module as shown in the following picture. Between the fuses is a small printedcircuit 

board (PCB) that sets the power adapter to the desired ac mains voltage. 

When handling the fuse module, the PCB may slide out. 

Caution If the small PCB between the fuses has slipped out of place, slide it 

back into place in the fuse module, and verify that the voltage setting indicated in 

the window on the fuse module is correct. If the voltage setting is incorrect, 

simply slide the PCB out of the fuse module, rotate it 180° and slide it back into 

place.

Spare Fuse 

Caution Leaving the monitor's lead-acid batteries in a completely discharged 

state may result in permanent battery damage. The batteries should be kept fully 

charged. 

The amount of time you can operate the Propaq Encore on each battery charge depends 

upon many variables including active options, frequency of NIBP measurements, 

frequency and length of print strips, ambient temperature, battery age and condition, and 

what information is displayed.

92 Power sources Welch Allyn Propaq Encore Vital Signs Monitor 

For monitors without the Expansion Module or SpO 2 option, typical monitor operating 

time is about 2 hours at 25° C for a new, fully-charged battery. This is when all patient 

channels are active and measurements are taken every 15 minutes. 

For monitors without the Expansion Module but with the SpO 2 option, operating time is 

about 5 hours. 

For monitors with the Expansion Module and printer, SpO 2 and CO 2 options, typical 

operating time is about 3 hours under the above conditions when print strips are 

generated every 15 minutes. 

Monitor functions based on battery voltage 

As battery voltage drops during extended monitor battery operation, error messages are 

displayed and monitor functions are discontinued in order of priority. 

Checking battery voltage

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) 

telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast 

cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to 

fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field 

strength in the location in which the monitor is used exceeds the applicable RF compliance level 

above, the monitor should be observed to verify normal operation. If abnormal performance is 

observed, additional measures might be necessary, such as reorienting or relocating the monitor. 

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
