14.6.2 Setting Up the PAWP Measurement
1. Wedge the flotation catheter into the pulmonary artery. Then inflate the balloon and
pay attention to PA waveform changes on the screen.
2. After obtaining a stable PAWP waveform, press the [Freeze] key to freeze the
waveform and deflate the balloon.
3. You can adjust the PAWP scale to an appropriate position by adjusting
or
beside the [Adjust] button. Press the [Confirm] key to save one PAWP measurement.
4. If you need to start a new measurement, select [Next Measure].
WARNING
z Prolonged inflation can cause pulmonary hemorrhage, infarction or both. Inflate
the balloon for the minimum time necessary to get an accurate measurement.
z If the PAWP is greater than the PA (systolic), deflate the balloon and report the
incident in accordance with hospital policy. Because the pulmonary artery could be
accidentally ruptured, and the PAWP value derived will not reflect the patient’s
hemodynamic state, but will merely reflect the pressure in the catheter or balloon.
