pulmonary artery catheter normal pressure tracing curves


  • RAP: CVP tracing
  • RVP: rapid increase in systole with slow rise in diastole (differentiate from PA tracing)
  • pulmonary artery: diastolic pressure step up.
    • dicrotic notch appears related to PV pressure
  • wedge: similar to CVP with a wave and c wave

  • RAP: estimate of RV filling pressure
  • PAOP: estimate of LA pressure
  • wedge is similar in appearance but shifted right ward (takes longer to travel to the tip of the catheter)
