The pulmonary wedge pressure, also called pulmonary arterial wedge pressure, pulmonary capillary wedge pressure, pulmonary artery occlusion pressure, or cross-sectional pressure, is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch. It estimates the left atrial pressure.
