Swan sitting on its packaging. A pulmonary artery catheter (PAC), also known as a Swan-Ganz catheter or right heart catheter, is a balloon-tipped catheter that is inserted into a pulmonary artery in a procedure known as pulmonary artery catheterization or right heart catheterization.
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 right heart catheterization (commonly known as Swan-Ganz catheterization) gives the physician the mean pulmonary capillary wedge pressure, which is a reflection of the left atrial pressure. The left heart catheterization, on the other hand, gives the pressure in the left ventricle.
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]
The other thermodilution method is to sense the temperature change from a liquid injected in the proximal port of a Swan-Ganz to the distal port. Cardiac output is mathematically expressed by the following equation: = where CO = cardiac output (L/sec) SV = stroke volume (ml) HR = heart rate (bpm)
In addition, automated ECG interpretation incorporates diagnostic codes automatically into the charts. Medical monitor's embedded software can take care of the data coding according to these standards and send messages to the medical records application, which decodes them and incorporates the data into the adequate fields.
Impedance cardiography (ICG) is a non-invasive technology measuring total electrical conductivity of the thorax and its changes in time to process continuously a number of cardiodynamic parameters, such as stroke volume (SV), heart rate (HR), cardiac output (CO), ventricular ejection time (VET), pre-ejection period and used to detect the impedance changes caused by a high-frequency, low ...
The Carnival of the Animals (French: Le Carnaval des animaux) is a humorous musical suite of 14 movements, including "The Swan", by the French composer Camille Saint-Saëns. About 25 minutes in duration, it was written for private performance by two pianos and chamber ensemble; Saint-Saëns prohibited public performance of the work during his ...
