Pi meaning in oximeter - What is Perfusion Index (PI)

Generally speaking, you want to apply the sensor to the area that has the highest percentage.

Perfusion index is an indication of the pulse strength at the sensor site.

How to monitor my perfusion index? PI monitoring warrants further exploration for other clinical applications where information on peripheral perfusion or circulatory status would be useful.

Description: Please consult a medical professional for any queries.

Studies have shown that an increase in PI is an early indicator that general or epidural anesthesia has initiated peripheral blood vessel dilation, which typically occurs before the onset of anesthesia.
For most pulse oximeters for general use, the reading is unreliable or unavailable if PI is at or below 0.
When it comes to a high perfusion index, it means that you are OK; a high perfusion index indicates that the strength of the pulse to an area such as your toes is very strong.

    β€˜Scopes tend to be used for long durations at full brilliance. With 12 volts in and the LED at full brilliance, the XL4015 case temperature eventually rises above 60 degrees C. The microscope base doesn’t have much real estate for a heat sink and demands an ultra-reliable heat sink design (meaning no glue).

    Services. Services are used to break data up into logical entities, and contain specific chunks of data called characteristics. A service can have one or more characteristics, and each service distinguishes itself from other services by means of a unique numeric ID called a UUID, which can be either 16-bit (for officially adopted BLE Services) or 128-bit (for custom services).
