8. Press PURGE to automatically remove all air through the air column
detect sensor.
9. Press SALINE to automatically ush all air through the patient tubing and
stopcock.
10. Make sure the manifold valve closes and there is no space between the
valve and the end of the manifold.
11. Do a nal check to make sure all air has been removed from the entire
uid pathway.
1. Connect the patient catheter to the stopcock.
2. Connect the hand syringe to the stopcock.
3. Open the stopcock to the patient and aspirate blood with the hand syringe
to clear any air that may be in the catheter connection.
4. Turn the stopcock so that the patient is disconnected from ow.
5. If necessary, press and hold PURGE to purge additional contrast until
contrast ows out of the stopcock.
6. Press CANCEL.
Caution
Make sure the connection between the patient tubing and the
catheter is purged of air.
Zero the transducer before recording any pressure waveforms. To zero the
pressure transducer:
1. Open the stopcock to air.
2. Hold the stopcock and pressure transducer at midaxillary.
Tip
Before recording pressure waveforms, ush saline through the patient
tubing. Contrast in the patient tubing will damp the pressure signal.
