central venous oxygen saturation


Also found in: Acronyms.

central venous oxygen saturation (CVSO2)

the oxygen saturation in the vena cava. The CVSO2 is measured through a central venous catheter and is useful in measuring cardiac output. A reading of less than 55% usually indicates a falling cardiac output and probable cardiac failure.

central venous oxygen saturation

,

ScvO2.

The oxygen saturation of venous blood sampled from the superior vena cava. It is slightly less than the oxygen saturation from the lower body (as measured in the inferior vena cava) because of the increased oxygen saturation that occurs in the brain and upper body.
