  1. ScvO2 central venous oxygen saturation
  2. Initial model included covariates of age, Sequential Organ Failure Assessment score, central venous pressure, mean arterial pressure, and norepinephrine-equivalent vasopressor dose. Linear regression R2 =0.27. Areas under the curve for the logistic regression models were 0.84 for ScvO2 <60 % and 0.75 for ScvO2 <70 %
