What are the normal number when checking my pulse oxygen

Hello, Anon.

Thank you for posting.

Oxygen saturation measures how much oxygen the blood is carrying compared with its full capacity.

Generally, an SpO2 of greater than 95% is generally considered to be normal.
An SpO2 of 92% or less (at sea level) suggests hypoxemia.
In a patient with acute respiratory illness (e.g., influenza) or breathing difficulty (e.g, an asthma attack), an SpO2 of 92% or less may indicate a need for oxygen supplementation.
In a patient with stable chronic disease (e.g., COPD), a SpO2 of 92% or less should prompt referral for further investigation of the need for long-term oxygen therapy.
