Table 3 Diagnostic performances of ΔCI PC and ΔCI ECOM in predicting fluid responsiveness

From: Can endotracheal bioimpedance cardiography assess hemodynamic response to passive leg raising following cardiac surgery?

  ΔCIPC ΔCIECOM
ROCAUC 0.72 (0.50-0.88) 0.81 (0.61-0.94)
Cutoff value (%) 6 3
Sensitivity 50 (23-77) 93 (66-100)
Specificity 91 (59-100) 73 (39-94)
Positive likelihood ratio 5.5 (3.2-9.6) 3.4 (2.3-5.0)
Negative likelihood ratio 0.6 (0.1-3.8) 0.1 (0.0-0.8)
  1. Values are given with 95% confidence interval.
  2. ΔCI ECOM  = change in cardiac index ECOM during passive leg raising; ΔCI PC  = change in cardiac index pulse contour analysis during passive leg raising; ROC AUC  = area under the receiver operated characteristics curve.
