What unit is used to measure oxygen saturation?

Oxygen saturation is measured as a percentage, indicating the level of oxygen bound to hemoglobin in the blood compared to the total hemoglobin that can bind oxygen. Clinicians often refer to this value when assessing respiratory function and the effectiveness of oxygen therapy. A normal oxygen saturation level typically ranges from 95% to 100%, and this measurement is vital in clinical settings to determine if a patient is receiving adequate oxygenation.

Other units such as cubic centimeters, heartbeats per minute, and pascals are used for different healthcare measurements, but they do not apply to oxygen saturation. Cubic centimeters measure volume, heartbeats per minute indicates heart rate, and pascals measure pressure. Therefore, the context of the question clearly identifies percentage as the correct unit for measuring oxygen saturation.
