Abstract
The Swan-Ganz catheter was introduced into general clinical medicine in 1970 and quickly
gained widespread use in the management of critically ill patients. The device offers
highly sophisticated physiologic information; however, in many instances, only the
wedge pressure and the cardiac output are utilized when managing acutely ill patients.
The purpose of this review is to illustrate and explain the array of physiologic data
available from the Swan-Ganz catheter in most circumstances. A basic understanding
of the information that can be obtained with the Swan-Ganz catheter is quite useful
in the diagnosis and management of a variety of cardiovascular disorders. In addition,
the Swan-Ganz catheter can be a helpful tool for teaching cardiovascular pathophysiology.
