Fig. 6From: Changes in stroke volume induced by lung recruitment maneuver can predict fluid responsiveness during intraoperative lung-protective ventilation in prone positionGray zone for ΔSVLRM. Blue and red lines denote sensitivity and specificity, respectively. The gray zone indicates the inconclusive range for each variable. ΔSVLRM, decrease in stroke volume by lung recruitment maneuver; SV, stroke volume; LRM, lung recruitment maneuverBack to article page
