28 Monitoring Welch Allyn Propaq CS Vital Signs Monitor
Perform Invasive Blood Pressure (IBP) monitoring
1. Inspect the transducer cable and transducer dome for wear, breakage, or fraying.
Replace any worn or broken accessory.
2. Set up the transducer according to your hospital's procedures. Always refer to the
transducer manufacturer’s Directions for Use. If the transducer is a disposable unit
with separate cable, connect the transducer to the transducer cable.
3. Plug the transducer (or transducer cable) into an invasive pressure connector on the
monitor left side panel.
4. To zero the transducer, open the transducer's stopcock to atmospheric air. Wait a few
seconds for the transducer to settle.
Before zeroing, make sure the transducer cable is properly connected to the monitor
and the transducer is open to atmospheric air and positioned at the same level as the
patient’s heart. The monitor will not zero the transducer if the pressure waveform is
pulsatile, there is too much signal noise, or the transducer’s offset is too great.
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.
WARNING Before you use a Propaq CS monitor 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 and alarm limit settings.
WARNING For best product performance and measurement accuracy, use only
accessories supplied by Welch Allyn or recommended in Welch Allyn Products
and Accessories. Use accessories according to your facility’s standards and the
manufacturer’s recommendations. Always refer to the manufacturer’s Directions
for Use. Do not use light-sensitive disposable transducers.
