A flow directed catheter, commonly known as a pulmonary artery catheter (PAC), Swan-Ganz catheter, or right heart catheter, is a specialized medical device used for monitoring various hemodynamic parameters within the cardiovascular system. The procedure involves the insertion and placement of this catheter into a major vein, typically located in the neck, upper chest, or groin, to facilitate accurate monitoring of cardiac pressures and other vital metrics. The catheter is designed to be advanced through the venous system into the right atrium and subsequently into the pulmonary artery, allowing for the assessment of pulmonary artery pressure, pulmonary capillary wedge pressure, and cardiac output. Additionally, it provides critical information regarding mixed venous oxygen saturation and oxygen levels in the right heart chambers. This procedure is essential for patients requiring close monitoring of their cardiovascular status, particularly in critical care settings, where precise measurements can guide treatment decisions and interventions.
