Step 4: Once the , it will display your results on the screen. Measuring the Perfusion Index The most widely used monitoring tool to keep track of the perfusion index is the pulse oximeter.

What is a pulse oximeter and how to use it

Severe artifacts, such as motion or light interference, are amplified in the presence of low perfusion. It has a high correlation with the capillary refill, just as the key-to-toe temperature distinction.

What is a pulse oximeter and how to use it

Have you ever wondered what the Perfusion Index numbers in your pulse oximeters mean? Common reasons of poor perfusion include diabetes, obesity, blood clots and peripheral artery diseases. The when attached to your finger, earlobe or toe beams multiple small lights that pass through the blog in your body part the oximeter is attached too, thus measuring the amount of oxygen in your blood.

A Guide To The Perfusion Index In Pulse Oximeters

By posting, you are agreeing to our and understand that all information is taken at your own risk. In moderate cases, SpO2 is usually reduced to 94-95%. The PI Perfusion Index derived from the instrument addresses the peripheral perfusion that can be measured ceaselessly without infiltrating the body.


What is Perfusion Index in a Pulse Oximeter?

The technique of pulse oximetry does have limitations and these limitations are enhanced with improper use, such as incorrect sensor selection, poor sensor placement, or a limited understanding of the capabilities of pulse oximetry. For most pulse oximeters for general use, the reading is unreliable or unavailable if PI is at or below 0. A strong pulse strength or more bars is a good sign that you will get a more accurate reading.


Pulse Oximetry and Low Perfusion

In this case, it is a preferred approach as compared to qualitative ones like foot warmth. Another thing to remember is that nail polish or fake fingernails can cause false readings, so I recommended removing either of these before taking your reading.
