The saturated percentage of oxygen refers to the maximum amount of oxygen that can dissolve in a liquid, typically water or blood. It is usually expressed as a percentage, indicating the saturation level of oxygen at a given temperature and pressure. In the human body, oxygen saturation levels in the blood are typically measured using a pulse oximeter and are considered normal when they are around 95-100%.
