29 3 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).
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.
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, SpO2, C-Lock, and NIBP due to intermittent ECG lead wire connections.
32 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor 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.
Reference Guide Patient monitoring 7. 33 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.
34 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor Impedance pneumography selections If your Propaq Encore includes the Impedance Pneumography Option, the following selection is also available: RESP SZE Selects the RESP waveform size. The Size function “increases” and “decreases” the ECG or RESP waveform size. Each time you press a SIZE button, the waveform approximately doubles in height. When you reach the largest waveform size, the next press displays the smallest size.
Reference Guide Patient monitoring Note 35 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.
36 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor 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.
Reference Guide Patient monitoring 37 NOISY SIGNAL, CHECK ELECTRODES. Electrodes are making poor contact and may be dried out. Replace electrodes. 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.

42 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor 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.
Reference Guide Patient monitoring Improve NIBP accuracy with Smartcuf 43 ® 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.
44 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor 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.
Reference Guide Patient monitoring Cuff applied evenly and snugly with bottom edge of cuff one inch above antecubital fossa 45 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.

You can therefore perform intermittent or “spot-check” SpO2 monitoring. 1. While monitoring SpO2, remove the SpO2 sensor from the patient, but leave it connected to the monitor.
Reference Guide Patient monitoring 57 Capnography (CO2) Intended use The Propaq’s Capnography (CO2) option is intended to noninvasively measure the following vital signs or events: End-tidal CO2 (ETCO2), Inspired CO2 (INCO2), Breath Rate, and Apnea. The CO2 option is available as mainstream CO2, sidestream CO2, or Dualstream CO2. Although Dualstream CO2 provides both mainstream CO2 and sidestream CO2 monitoring, only one method can be used at a time.
58 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor Sidestream CO2 option The sidestream CO2 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.
Reference Guide Patient monitoring 59 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.
60 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor SOURCE Changes between mainstream CO2 and sidestream CO2 monitoring (if both options are installed), or disables CO2 monitoring Setting CO2 SOURCE to OFF allows you to disable CO2 monitoring without removing the sensor. When the CO2 SOURCE is set to OFF, the Propaq displays OFF for CO2 numerics.
Reference Guide Patient monitoring 61 Mainstream CO2 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 CO2 sensor by blowing through it directly. Always blow through an attached airway adapter.
62 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor Note When disconnecting the airway adapter from the ventilator circuit, always detach the CO2 sensor from the airway adapter before removing the airway adapter from the ventilator circuit. How to set up the CO2 channel and alarm limits After you connect the mainstream CO2 sensor or sidestream CO2 watertrap adapter, follow these steps to set up the CO2 channel and alarm limits.
Reference Guide Patient monitoring 63 6. Press RESPONSE to select either NORMAL, SLOW, or FAST. The FAST setting is recommended where a sudden step change in ETCO2 is of concern, such as that induced by an air embolus in certain neurosurgical procedures. A SLOW response will decrease ETCO2 false alarms when breath morphology varies considerably from one breath to the next. The default setting is NORMAL.
64 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor Sidestream CO2 monitoring WARNING If the sidestream CO2 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 CO2 option. WARNING Do not use sidestream CO2 if flammable anesthetic gases are in use.
Reference Guide Patient monitoring 65 Connect to a nonintubated patient 1. Position the cannula on the patient according to the manufacturer’s instructions. WARNING The cannula is disposable and should only be used for a single patient. Do not reuse the cannula for another patient. WARNING If oxygen is being delivered while using sidestream CO2 , be sure to use a CO2 Sampling and O2 Delivery Cannula. Using a different type of cannula could obstruct oxygen delivery.

77 5 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.
78 Trends Welch Allyn Propaq Encore Vital Signs Monitor 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. NIBP trends A maximum of 128 NIBP readings are collected (up to 8 hours). NIBP is not measured continuously like other vital sign parameters.
79 6 Printing Printing patient data Printing waveforms 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.

Reference Guide Power sources 91 Power Switch Fuse Fuse Module Voltage Selector and Indicator Spare Fuse Caution Make sure the voltage selector indicates the proper ac input voltage. If you change the adapter voltage setting, you must replace all fuses to match the appropriate type specified on the bottom of the power adapter. The only fuses contained in the power adapter when shipped from the factory are fuses specified for the original adapter input voltage setting.
92 Power sources Welch Allyn Propaq Encore Vital Signs Monitor For monitors without the Expansion Module or SpO2 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 SpO2 option, operating time is about 5 hours.
93 9 Care and maintenance Avoid electrostatic discharge When humidity in the working environment decreases, the human body and other insulators can become charged with static electricity due to friction. To prevent unwanted electrostatic discharge (ESD), follow these standard guidelines: • Maintain the recommended humidity of 40% to 60% in the work environment. • Dissipate electrostatic charge before performing routine operator maintenance.
94 Care and maintenance d. Welch Allyn Propaq Encore Vital Signs Monitor The mainstream CO2 sensor may also be disinfected with Wex-cide. Follow the disinfectant manufacturer’s instructions. Do not leave Wex-cide on sensor longer than 30 minutes. Thoroughly clean off residue with water-dampened cloth. Prolonged exposure of the sensor to Wex-cide will damage the sensor. Caution Do not autoclave this product or its accessories. Do not immerse the monitor in liquid when cleaning.
