A member asked:

Oximeter show spo2 level on left hand 97 and on right it shows 94 which is correct?

A doctor has provided 1 answer

Both are probably within the precision of the device you are using, as levels can vary over time, and the values will be different from side to side. Both are within normal range. Best way to use pulse oximeter is to follow trends, that is, changes over time. If levels are steadily dropping, contact your doctor.
