What unit is used to measure oxygen saturation?

Oxygen saturation is measured in percentage, which indicates the level of oxygen bound to hemoglobin in the blood compared to the total capacity of hemoglobin to bind oxygen. This measurement is crucial in assessing a person's respiratory function and the efficiency of oxygen transport in the bloodstream. A typical oxygen saturation level for a healthy individual ranges from 95% to 100%.

Cubic centimeters are generally used to measure volume, heartbeats per minute is a unit for measuring heart rate, and pascals are a unit for measuring pressure. Therefore, these units do not apply to the measurement of oxygen saturation, making percentage the only appropriate choice in this context.
