38 Patient monitoring Welch Allyn Propaq Encore Vital Signs Monitor 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. P 1 The message NOT ZEROED (or NO ZERO, depending on the zone) immediately appears in the blood pressure numerics window for the invasive pressure channel being used. 18:45:28 III 1 mV cm MON NIBP T1 102.3 F 1. To zero the transducer, open the transducer's stopcock to atmospheric air. Allow a few seconds for the transducer to settle. 2. If the ZERO menu is not displayed, press the following Propaq Encore buttons: INV PRS, then ZERO P1 (or ZERO P2). The word ZEROING appears in the numerics window during zeroing. The button label changes to CANCEL to allow you to cancel the zeroing process if necessary 3. Wait for a tone to briefly sound and the word ZEROED to appear in the blood pressure numerics window. You will then see the pressure scale to the left of the waveform, and the pressure numerics appear. 4. Close the transducer's stopcock.

If the transducer will not zero, the words ZERO REJECTED (or NO ZERO, depending on zone) will appear in the numerics window. Press CANCEL and try zeroing again. You won’t see the pressure values and the scales until an acceptable zero reference is established. 6. Check that the transducer is open to atmospheric air and that it is properly connected to the Propaq Encore, then try zeroing again. The Propaq Encore will not allow zeroing to occur if the pressure waveform is pulsatile, if there is too much noise in the signal
Reference Guide Patient monitoring 39 Setting up the pressure channel or if the transducer’s offset is too great. Once the channel is zeroed, the pressure scale appears next to the waveform. If the transducer still does not zero, try another transducer or another cable. Press INV PRS to set the invasive pressure channel selections: RANGE, RESCALE, and ZERO P1/ZERO P2. Press MORE to set LABEL P1/LABEL P2 and FORMAT 1/FORMAT 2. Setting the invasive pressure alarms Set the alarm limits according to your hospital's standards. 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.
