An SaO 2 (arterial oxygen saturation) value below 90% causes hypoxemia (which can also be caused by anemia). Hypoxemia due to low SaO is indicated by cyanosis. Oxygen saturation can be measured in different tissues: 1  Venous oxygen saturation (SvO 2) is measured to see how much oxygen the body consumes.2  Under clinical treatment, a SvO 2 below 60% indicates that the body is in lack of oxygen, and ischemic diseases occur.n medicine, oxygen saturation (SO 2), 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.
