Pulseoximeter finger readings variations
Yesterday at my pulmonologist’s office as is typical, my O2 level was read using my left pointer finger with a pulseoximeter and was 91 which was concerning to me. At my request, we also measured the middle finger of my right hand and it was 95. This morning upon awakening I took a reading from the same fingers and again, the same difference. So I googled the subject and found this st udy:

My question and given the statistical significance conclusion, it seems I should always insist that my right middle finger be used yet I am also wondering if anyone has discussed this finding with their pulmonologist when assessing their lung function? I was surprised.

@desertdwellerjh Perhaps just offer your middle finger for the test each time? If questioned, explain why.
I actually though using the middle finger was the standard, our clinic has always done it that way.

2 ReactionsThanks! I do not recall at any time getting a specific instruction for the middle finger on the right hand. I will be offering that finger from now on!
@desertdwellerjh
I often would like to offer my middle finger to someone but I try to be good 🙂

3 ReactionsI have definitely noticed the difference between the index finger and middle finger. My readings are never low enough to raise an issue, either finger, but if I did ever have concern, I have learned the middle finger has the highest reading. I haven't read the article offered on the subject so not sure if the difference is meaningful.
