Figure 1

ROC curve analysis illustrating the usefulness of ScvO₂ measurement before blood transfusion in order to predict a minimal 5% increase in ScvO₂ after BT. The threshold value for ScvO₂ with the best sensitivity and best specificity was 69.5% (*sensitivity: 82%, specificity: 76%; area under the curve: 0.831 ± 0.059). Adapted from [7] with permission.

Figure 2

Individual evolutions in ScvO₂ before and after blood transfusion (BT) according to agreement (Reco+) or not (Reco-) with the SRLF recommendations for transfusion and according to the ScvO₂ before transfusion (< or ≥ 70%). Adapted from [7] with permission.
