Perform Invasive Blood Pressure (IBP) Monitoring
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.
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.
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.
For best product performance and measurement accuracy, use only accessories supplied by Protocol
Systems or recommended in the Protocol Systems Products and Accessories booklet. 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.
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.
