WebMixed venous oxygen saturation (SVO2) can help to determine whether the cardiac output and oxygen delivery is high enough to meet a patient's needs. It can be very useful if measured before and after changes are made to cardiac medications or mechanical ventilation, particularly in unstable patients. What is SvO2? WebSep 5, 2024 · Mixed venous oxygen saturation (SvO 2) is a measurement of whole body oxygenation.
