PCWP Waveform Interpretation Question

  1. Would appreciate some tutoring from my colleagues...! what reference points are used to determine/read the PCWP? Is it the point between the A and V wave or what? Any help appreciated because it is unclear from several ref books and in some cases contradictory. Thanks again and please feel free to e me your help and if I can offer any return help please do not hesitate to contact me. I am in the Los Angeles area and happy to provide info about local hospitals etc as best I can.

    The wedge pressure is read at the peak of the waveform at end expiration.

    It also depends on if the patient is ventilated or not. If the patient is on a vent where you measrue the wave form is different.
