(Page 131).
ratio of the central venous pressure (CVP) to the mean arterial pressure (HR × CVP / MAP)). ◆ LOD score uses the heart rate and the systolic blood pressure. A comparison among them, suggests that the MODS and the SOFA scores are both reliable outcome predictors, but the cardiovascular dysfunction/failure is better related to outcome with the SOFA score than with the MODS score [8]. It is also easier to compute.
