What is the purpose of swan-ganz catheter?

A Swan-Ganz catheter, also known as a pulmonary artery catheter, is used to monitor hemodynamic parameters in critically ill patients. It measures pressures in the heart and pulmonary artery, allowing for assessment of cardiac function, fluid status, and response to treatment. This catheter can also facilitate the administration of medications and fluids directly into the pulmonary artery. Its primary purpose is to guide clinical decision-making in managing conditions such as heart failure, shock, and severe respiratory illnesses.
