PCWP (Pulmonary Capillary Wedge Pressure), PAW (Pulmonary Artery Wedge), and PAO (Pulmonary Artery Occlusion) all refer to the pressure measurement obtained when the balloon on a pulmonary artery catheter is inflated. PVR (Pulmonary Vascular Resistance) is not a pressure measurement but a calculated value.
