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.

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.

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.

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.
