I.PCWP stands for pulmonary capillary wedge pressure and measures the pressure behind the inflated balloon on the pulmonary artery catheter, indicating left ventricular end-diastolic pressure. 
II.PAW stands for pulmonary artery wedge pressure, which is another term for PCWP. 
III.PAO stands for pulmonary artery occlusion pressure, which is also another term for PCWP. 
IV.PVR stands for pulmonary vascular resistance and is not related to measuring pressures with a pulmonary artery catheter.
