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:
https://pmc.ncbi.nlm.nih.gov/articles/PMC4627972/
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 🙂

6 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.

1 Reactionthe highest readings I get are using my index finger and not the middle finger. Maybe it depends on the person as to which finger reads the highest. But who knows which reading is the most accurate!
