Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.

In crude terms, this measurement compares left and right cardiac activity and calculates preload and afterload flow and pressures which, theoretically, can be stabilized or adjusted with drugs to either constrict or dilate the vessels (to raise or lower, respectively, the pressure of blood flowing to the lungs), in order to maximize oxygen for ...

PAOP and PVR cannot be measured directly with echocardiography. Therefore, diagnosis of PAH requires right-sided cardiac catheterization. A Swan-Ganz catheter can also measure the cardiac output; this can be used to calculate the cardiac index, which is far more important in measuring disease severity than the pulmonary arterial pressure.
