pulmonary artery catheter

A pulmonary artery catheter, also known as a Swan-Ganz catheter, is a thin, flexible tube inserted into a large vein and threaded into the pulmonary artery in the lungs. It allows doctors to measure important heart and lung functions, such as blood pressure in the lungs, oxygen levels, and how well the heart is pumping. This information helps diagnose and manage complex conditions like heart failure, shock, or lung issues. The procedure provides real-time data, guiding treatment decisions, especially during critical care or surgeries.
