What is normal perfusion?
0.02% to 20%
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.
What is low perfusion?
Low perfusion is the product of reduced peripheral blood flow and subsequent reduction in the detectable signal at the sensor site.
What do we need for perfusion?
The human body requires blood vessels to dilate and contract daily to maintain adequate perfusion. As you stand up, sit down, exercise, sleep, etc., various changes in body position and metabolism require vessels to adjust their diameter (also known as vascular tone).
What causes poor skin perfusion?
