Prolonged inflation can cause pulmonary hemorrhage, infarction or both. Inflate the balloon for the
minimum time necessary to get an accurate measurement.
If the PAWP is greater than the PA (systolic), deflate the balloon and report the incident in accordance with

will not reflect the patient’s hemodynamic state, but will merely reflect the pressure in the catheter or
balloon.
