he pulmonary arterial catheter (PAC), also known as the Swan-Ganz catheter, represents one of the most significant advances in critical care medicine for hemodynamic monitoring. This specialized diagnostic tool is inserted through a central vein and advanced through the right heart chambers into the pulmonary artery, allowing direct measurement of cardiac pressures and function in critically ill patients.
