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 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)
Swan was born on 1 June 1922 in Sligo Ireland. His parents were both physicians, Harold John Swan and Marcella Bertile Swan née Kelly. His mother called him "Jeremy" to limit confusion and the name stuck throughout his life. Swan's early education was at Castle Rock School.
They are connected to an oscillator and subsequent frequency demodulation electronics to obtain digital waveforms. During inspiration the cross-sectional area of the rib cage and abdomen increases altering the self-inductance of the coils and the frequency of their oscillation, with the increase in cross-sectional area proportional to lung volumes.
An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
Lissajous curves can also be generated using an oscilloscope (as illustrated). An octopus circuit can be used to demonstrate the waveform images on an oscilloscope. Two phase-shifted sinusoid inputs are applied to the oscilloscope in X-Y mode and the phase relationship between the signals is presented as a Lissajous figure.
Collapse theories stand in opposition to many-worlds interpretation theories, in that they hold that a process of wave function collapse curtails the branching of the wave function and removes unobserved behaviour.
