High: Above 100%
About Oxygen Saturation
Oxygen saturation measures the percentage of oxygen in the blood.
The reasons for low O2Sat
Low oxygen saturation may be due to lung disease, sleep apnea, or high altitude exposure. Oxygen therapy and improving lung function can help.
The reasons for elevated O2Sat
High oxygen saturation is usually not concerning unless excessive oxygen therapy is used, which may cause oxidative stress.
Is it bad too have too high/low O2Sat?
Low oxygen saturation can cause confusion, dizziness, and respiratory distress.
High oxygen saturation is usually not dangerous but, in rare cases, may contribute to oxidative stress in tissues and cells.
