Invasive Pressure
Propaq Encore Reference Guide 51 Welch Allyn
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
