What is a good reading for a pulse oximeter?

According to the Mayo Clinic, normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low, and indicate the need for supplemental oxygen.

Most oximeters give a reading 2% over or 2% under what your saturation would be if obtained by an arterial blood gas. … The oximeter reading may be less accurate if a person is wearing nail polish, artificial nails, has cold hands, or has poor circulation.

What is the normal SpO2 in adults?

A normal healthy person should be able to achieve normal blood oxygen saturation levels (SpO2) of 94% to 99%. For patients with mild respiratory diseases, the SpO2 should be 90% or above. Supplementary oxygen should be used if SpO2 level falls below 90%, which is unacceptable for a prolonged period of time.
