While introducing the Swan-ganz catheter, its placement in the pulmonary aery can be identified by the following pressure tracing:
C i.e. PA pressure tracing has diacrotic notch from closure of pulmonary valve
Diastolic pressure is lower in PA than in RV
Diatolic pressure is higher in PA than in RV
PA pressure tracing has diacrotic notch from closure of pulmonary valve
RV pressure tracing for plateau and sharp drop in early diastole
