After Swan developed the initial balloon tip, Ganz used Fronek's idea and added a small thermistor (temperature probe) about 3 cm behind the tip. 10 ml of saline (0.9% NaCl) under 10 °C or room temperature (not as accurate) is injected into an opening in the right atrium. As this cooler fluid passes the tip thermistor, a very brief drop in the ...
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.
An anesthetic machine with integrated systems for monitoring of several vital parameters, including blood pressure and heart rate. Monitoring of vital parameters can include several of the ones mentioned above, and most commonly include at least blood pressure and heart rate, and preferably also pulse oximetry and respiratory rate.
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)
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]
A photoplethysmogram (PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue. [1] [2] A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. [3]
Amplitude integrated electroencephalography (aEEG), cerebral function monitoring (CFM) or continuous electroencephalogram (CEEG) is a technique for monitoring brain function in intensive care settings over longer periods of time than the traditional electroencephalogram (EEG), typically hours to days.
