ScvO2 (Central venous oxygen saturation)

ScvO2, or central venous oxygen saturation, measures the percentage of oxygen remaining in the blood returning to the heart via a central vein. It indicates how effectively the body is using oxygen delivered to tissues. A normal range helps clinicians assess if tissues are receiving enough oxygen and whether the heart and lungs are functioning properly. Low levels may suggest inadequate oxygen delivery or increased oxygen use by tissues, while high levels can indicate issues like poor tissue utilization or cardiac problems. Overall, ScvO2 provides valuable insight into a patient's oxygenation status and helps guide treatment decisions.
