The study investigated the effect of acute normovolaemic haemodilution on haemodynamics, blood flow and oxygen transport variables with regard to skeletal muscle tissue oxygenation in a canine model. ⋯ In acute normovolaemic haemodilution to the level of Hct of 25%, the ratio between tPO2 and cardiac index decreases in the healthy dog, indicating an uneconomic relation at the threshold of Hct of 25%.
