pulmonary artery









































a pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. the largest pulmonary artery is the "main pulmonary artery" or "pulmonary trunk" from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli.

pulmonary artery catheter









































pulmonary artery catheterization (pac), or right heart catheterization, is the insertion of a catheter into a pulmonary artery. its purpose is diagnostic; it is used to detect heart failure or sepsis, monitor therapy, and evaluate the effects of drugs. the pulmonary artery catheter allows direct, simultaneous measurement of pressures in the right atrium, right ventricle, pulmonary artery, and the filling pressure ("wedge" pressure) of the left atrium. the pulmonary artery catheter is frequently referred to as a swan-ganz catheter, in honor of its inventors jeremy swan and william ganz, from cedars-sinai medical center.
