Legend: PPV: pulse pressure variations induced by the respiratory mechanical ventilation displayed by the scope; ΔCVP: difference between CVP before and CVP during ARM; ΔMAP : difference between MAP before and during ARM ; ΔPP : difference between pulse pressure (SAP-DAP) before and pulse pressure during ARM ; ΔPVP : difference between PVP before and PVP during ARM; NPV: negative predictive value; PPV: positive predictive value
The P value represents the pairwise comparison of ROC curves between the ΔPVP ROC curve and each tested ROC curves
