A member asked:

What finger are you actually supposed to check your oxygen level on? anytime i go to the dr theyre using the left i googled it and it says the right hand so wich hand and finger are correct?

A doctor has provided 1 answer

Any finger on either hand should have the same blood oxygen content. We occasionally look for different numbers in newborns as a sign of a heart defect. (Different flow to different sides with defect) That is not an issue for regular adults or older kids.
