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 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.
