Perfusion - Wikipedia

WebThe perfusion index is calculated by dividing the pulsatile signal (AC) by the non-pulsatile signal (DC), multiplied by 100. This is then expressed as a percentage which ranges from 0.02% to 20%. The perfusion index can also be an indication of how reliable the reading from the pulse oximeter is.

WebA peripheral perfusion index based on analysis of the pulse oximetry signal has been implemented in monitoring systems as an index of peripheral perfusion. No data on the variation of this index in the normal population are available, and clinical application of this variable in critically ill patients has not been reported.

In 1935, German physician Karl Matthes (1905–1962) developed the first two-wavelength ear O2 saturation meter with red and green filters (later red and infrared filters). It was the first device to measure O2 saturation. The original oximeter was made by Glenn Allan Millikan in the 1940s. In 1943 and as published in 1949, Earl Wood added a pressure capsule to squeeze blood out of the ear so as to obtain an abs…
