    While introducing the Swan-ganz catheter, its placement in the pulmonary artern can be identified by the following pressure tracing:
    a) Diastolic pressure is lower in PA than in RV
    b) Diastolic pressure is higher in PA than in RV.
    c) PA pressure tracing has diacrotic notch from closure of pulmonary valve.
    d) RV pressure tracing for plateau and sharp drop in early diastole.

    We know that diatolic pressure is higher in PA than RV, and also that the diacrotic notch is present in the pressure tracing...but which amongst the two is used to confirm the position of swan ganz???

    Oxford Textbook of Surgery says 2/ed Chapter 40.6
    Quote:

    The waveform becomes markedly pulsatile as the catheter passes through the tricuspid valve into the right ventricle.

    Passage into the pulmonary artery is shown by a rise in the diastolic pressure.

    Advancing the catheter further causes it to impact into a peripheral pulmonary arteriole and the waveform changes once again to show pulmonary capillary-wedge pressure. pl.correct,if any mistake
