The passage of the catheter may be monitored by dynamic pressure readings from the catheter tip or with the aid of fluoroscopy. The standard pulmonary artery catheter has two lumens (Swan-Ganz) and is equipped with an inflatable balloon at the tip, which facilitates its placement into the pulmonary artery through the flow of blood. The balloon ...
William Ganz (January 7, 1919 – November 10, 2009) was a Slovakia-born American cardiologist who co-invented the pulmonary artery catheter, often referred to as the Swan-Ganz catheter, with Jeremy Swan in 1970. [1] The catheter is used to monitor heart conditions, especially in intensive care units.
The historically significant Swan-Ganz multi-lumen catheter allows reproducible calculation of cardiac output from a measured time-temperature curve, also known as the thermodilution curve. Thermistor technology enabled the observations that low CO registers temperature change slowly and high CO registers temperature change rapidly. The degree ...
Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.

He attended medical school at Trinity College Dublin in Dublin but earned his degree from St. Thomas's Hospital, London, England graduating in 1945. Swan was also an intern and junior resident at St. Thomas's Hospital from 1945 to 1946. He then entered the Royal Air Force medical service from 1946 to 1948, being stationed in Iraq. [8]
Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart.This is done both for diagnostic and interventional purposes. A common example of cardiac catheterization is coronary catheterization that involves catheterization of the coronary arteries for coronary artery disease and myocardial infarctions ("heart attacks").
Cardiogenic shock is a medical emergency resulting from inadequate blood flow to the body's organs due to the dysfunction of the heart.Signs of inadequate blood flow include low urine production (<30 mL/hour), cool arms and legs, and decreased level of consciousness.
