WebOct 24, 2024 · Venous oxygen saturation (SvO2) is a measure of the oxygen content of the blood returning to the right side of the heart after perfusing the entire body. When the oxygen supply is insufficient to meet the metabolic demands of the tissues, an abnormal SvO2 ensues and reflects an inadequacy in the systemic oxygenation. WebOct 1, 1999 · On admission to the ICU a blood sample for SvO 2 is routinely obtained in all patients. Oxygen saturation is measured in an OSM3 Hemoximeter (Radiometer, Copenhagen).
