A comprehensive 1999 review of pulse oximeters published in “Critical Care” noted that, on average, oximeters are accurate within 2 percent for oxygen saturations of 90 percent or more 1.Oximeters are far less reliable, however, once the …
Normal perfusion index reading
Did you know?
WebPulse oximetry is a test used to measure the oxygen level (oxygen saturation) of the blood. It is an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs. A clip-like device called a probe is placed on a body part, such as a finger or ear lobe. WebObjective: Peripheral perfusion in critically ill patients frequently is assessed by use of clinical signs. Recently, the pulse oximetry signal has been suggested to reflect changes in peripheral perfusion. A peripheral perfusion index based on analysis of the pulse oximetry signal has been implemented in monitoring systems as an index of peripheral perfusion.

The normal perfusion index (PI) ranges from 0.02% to 20% showing weak to strong pulse strength. How accurate is it? You can never say that your oximeter is 100% accurate. It can show a 2% over or 2% under due to your arterial blood gas or mechanical fault. Is 0.6 perfusion index good?
