Venous oxygen saturation as a physiologic transfusion trigger (2010) Benoit Vallet

Description

This review analyzes how venous oxygen saturation (SvO2 or ScvO2) integrates the body’s oxygen uptake-to-delivery (VO2-DO2) relationship. It evaluates SvO2 as a physiological tool to assess tolerance to anemia and function as a transfusion trigger in critical care settings, particularly by identifying tissue dysoxia.
