1. Pressure trace obtained from an anesthetized dog as a Swan-Ganz catheter is advanced through the right atrium, the right ventricle, through the main pulmonary artery, and into a branch of the pulmonary artery until it is “wedged.” The balloon is then deflated to show pulmonary artery pressure. Pulmonary capillary wedge pressure was about 8 mm Hg, and mean pulmonary artery pressure was about 17 mm Hg.
