What is svo2?

SvO2 stands for mixed venous oxygen saturation, which measures the amount of oxygen remaining in the blood after it has been pumped through the body, where it is used by the body's tissues. This measurement is obtained by analyzing a sample of venous blood, which is taken from the pulmonary artery.

SvO2 is an important indicator of a patient's oxygenation status, and it can provide essential information about their overall health status. It is used in critical care medicine to monitor the treatment of patients with circulatory or respiratory failure, trauma, and sepsis.

A normal SvO2 reading is between 60 and 80 percent. A higher reading indicates that the tissues are not extracting oxygen efficiently, while a lower reading indicates that oxygen delivery is insufficient to meet the body's metabolic demands. Both can indicate potential health problems and require further investigation and treatment.
