WebAug 21, 2024 · The measurement of Scvo2 has a controversial role in patients with sepsis. To review its value, remember that this measure is a surrogate for tissue oxygen consumption in the upper body. Decreased Scvo2 reflects an increased difference in oxygen leaving the left ventricle minus oxygen returning to the right ventricle. WebWhy there is still a place for the measurement of SvO2 or ScvO2 in patients with sepsis is discussed. The mixed venous oxygen saturation (SvO2) has been used to assess the adequacy of oxygen delivery (DO2) to oxygen consumption (VO2).
