12 Monitoring Invasive Pressure

Select Store Wedge to store the PAWP value.
6 Select Print Wedge to print the PAWP waveform and any reference waves or Record Wedge to
record them. While recording or printing, you cannot perform any more Wedge tasks.
WARNING
Prolonged inflation can cause pulmonary hemorrhage, infarction or both. Inflate the balloon for the
minimum time necessary to get an accurate measurement.
If the pulmonary artery flotation catheter drifts into the wedge position without inflation of the
balloon, the pulmonary artery pressure waveform assumes a wedged appearance. Take appropriate
action, in accordance with standard procedures, to correct the situation.
If the PAWP (mean) is greater than the PAP (systolic), deflate the balloon and report the incident in
accordance with hospital policy, because the pulmonary artery could be accidentally ruptured, and the
wedge value derived will not reflect the patient's hemodynamic state, but will merely reflect the
pressure in the catheter or balloon.
