Fig. 5From: Variation in central venous oxygen saturation to evaluate fluid responsiveness: a systematic review and meta-analysisBayes nomogram of the ΔScvO2 for defining fluid responsiveness. If an average-risk population has an assumed pretest probability of fluid responder of 50%, the probability of fluid responder will increase to 83% when the test is positive and decrease to 21% when the test is negativeBack to article page
