Swan-Ganz catheter
A pulmonary artery catheter used for advanced hemodynamic monitoring in critically ill patients.
Full Definition
The Swan-Ganz catheter, also known as a pulmonary artery catheter, is a multi-lumen device inserted through central venous access and floated into the pulmonary artery. It provides detailed hemodynamic measurements including cardiac output, pulmonary capillary wedge pressure, and mixed venous oxygen saturation. In surgical critical care, it's used for complex cases requiring precise fluid and vasopressor management, though its routine use has declined due to lack of mortality benefit and potential complications including arrhythmias and pulmonary artery rupture.
Usage
Usage note: Named after physicians Swan and Ganz; may be referred to as PA catheter or pulmonary artery catheter.
