INTRODUCTION. The pulmonary artery catheter (PAC; Swan-Ganz or right heart catheter) can be used for a variety of clinical purposes. Interpreting hemodynamic data from PACs is important for the diagnosis and management of a range of conditions including shock and pulmonary artery hypertension ().The interpretation of hemodynamic values and pressure …

Pulmonary artery occlusion pressure (Ppao) in a spontaneously breathing subject poststernotomy. The lines below the tracing indicate inspiration. Ppao falls relative to atmosphere during inspiration because the surrounding pleural pressure falls relative to atmospheric pressure.

The upper limit of normal of mean pulmonary artery pressure (MPAP) is 20 mm Hg , with a cut-off value for the diagnosis of pulmonary hypertension of 25 mm Hg . The upper limit of normal of the pulmonary artery wedge pressure (PAWP) is 12 mm Hg, with a cut-off value for the diagnosis of left heart failure usually agreed of 15 mm Hg . Errors up ...

The accuracy of pulmonary vascular pressure measurements is of great diagnostic and prognostic relevance. However, there is variability of zero leveling procedures, and the current recommendation of end-expiratory reading may not always be adequate. A review of physiological and anatomical data, sup …
Estimating pulmonary artery systolic pressure (PASP) - Medmastery
https://www.medmastery.com/magazine/estimating-pulmonary-artery-systolic-pressure-pasp
A normal pulmonary artery systolic pressure is less than 25 mmHg. Between 40 and 50 mmHg is considered a mild elevation. Anything greater than 50 mmHg is considered moderate elevation, and greater than 60 is considered severe. [00:04:30] In our example, the pressure was 43.9 mmHg or could be as high as 48.9, if we use the higher estimate for ...
Circulatory Pathways | Anatomy and Physiology II

As the pulmonary trunk reaches the superior surface of the heart, it curves posteriorly and rapidly bifurcates (divides) into two branches, a left and a right pulmonary artery. To prevent confusion between these vessels, it is important to refer to the vessel exiting the heart as the pulmonary trunk, rather than also calling it a pulmonary artery.

The pulmonary artery pressure tracing (Ppa) is evidenced by an abrupt rise in diastolic pressure . With further advancement, a fall in mean pressure and transition to an atrial waveform (see below) signals transition to a pulmonary artery occlusion (wedge) pressure (Ppw) ( …
