What is a Swan-Ganz catheter?

A Swan-Ganz catheter, also known as a pulmonary artery catheter, is a specialized medical device used to measure pressures in the heart and lungs. It is inserted through a major vein and threaded into the pulmonary artery, allowing for the assessment of cardiac output, pulmonary artery pressures, and other hemodynamic parameters. This information is crucial for managing patients with heart failure, shock, or severe respiratory conditions. The catheter also enables the delivery of medications and fluids directly into the bloodstream.
