Perfusion Index: what is it good for? Absolutely something!

The perfusion index is commonly found on pulse oximeters and cardiac monitors. It is a non-invasive measure of peripheral perfusion. But what are the reference ranges and clinical applications?

Finally someone who actually explained this to me so I could understand it. Thank you!

I was looking specifically for some intel about PI, and from like 7 videos, yours was actually the only one not only specifically talking about it, but also in general. Every other videos just never mention that PI in pulse oximeters exist.

Here's what I have noticed. For me it tends to be anywhere from about 1.5 to 6.5. It tends to be higher on my left index finger than on my right. It tends to be higher after eating. If I raise my finger over my head and point it straight up, it will rise well over 10. I'm not sure how to interpret this.

Box breathing based on pulse count increases perfusion index.

Mine 20% while doing wim Hoff method, now stable at 7.5%

Requires stability in all your extremity variables such as temp, positioning, motion, ect. Then, define typical baselines. By then, you can begin to get some confidence interpreting the waveform. Many's spot readings in the comments aren't going to be useful without a overall familiarity of their waveforms and averages.

My 1.2, do i have low blood circulation?

[nagoraopuyad]

I'm pi day work time 0.85 To, , 1 and sleep time 15to 21, ,very Bad

Ooooh.... As a nurse student, I'm so going to use it to determine which fingers are the best on a given problematic patient to punch holes into ;)

[fernizahahmad]

just want to say my Pi% bfore eat 0.4. after eat 11-15.

[nonamesawas]

My PI% was above 15 and 17....
I am 32 male lol

Nuts. I mean people nowadays are going nuts.
