What Is a Pulmonary Artery Catheter?
The pulmonary artery floating catheter, also known as the Swan-Ganz catheter, was first developed by Swan and Ganz in 1970 as a catheter with a balloon at the top. It is commonly used in clinical diagnosis of various cardiovascular diseases and guides clinical treatment.

- The pulmonary artery floating catheter, also known as the Swan-Ganz catheter, was first developed by Swan and Ganz in 1970 as a catheter with a balloon at the top. It is commonly used in clinical diagnosis of various cardiovascular diseases and guides clinical treatment.
- In recent years, due to the vigorous development of critical care medicine, Swan-Ganz catheters have been used for hemodynamic monitoring of critically ill patients.
- A Swan-Ganz catheter is inserted intravenously into the superior vena cava or inferior cavities, and passes through the right atrium, right ventricle, main pulmonary artery, and left or right arterial branches to the pulmonary arterioles. Through this catheter, the central venous pressure (CVP), right atrial pressure (RAP), right ventricular pressure (RVP), pulmonary systolic pressure (PASP), pulmonary diastolic pressure (PADP), mean pulmonary artery pressure (PAP), and pulmonary arterioles can be measured. Wedge pressure (PAWP, also known as pulmonary capillary wedge pressure, PCWP). In addition, the thermodilution method (thermodilution) was used to measure the cardiac output (cardiac output, co), and the cardiac index (CI), stroke volume (SV), and stroke index (SI) were calculated. Pulmonary vascular resistance (PVR) and systemic vascular resistance (SVR) can also be calculated. Provide clinicians with dynamic, accurate and reliable hemodynamic data and cardiac function status to guide clinical medication.
