Blood Oxygen Saturation (SO2), commonly referred to as "sats", measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen. At low partial pressures of oxygen, most hemoglobin is deoxygenated. Normal blood oxygen saturation levels for most healthy persons averages around 95% to 100%. A pulse oximeter is used to measure blood oxygen levels.
