Welch Allyn Propaq Encore Vital Signs Monitor
Preparation
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.
Preparing the transducer
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.
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.
Zeroing the transducer
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.
5.
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
