ROC curves of EtCO2, MAP, and HR variation to assess fluid responsiveness after a 500-ml fluid load. Mean arterial pressure (MAP), end-tidal carbon dioxide (EtCO2), and heart rate (HR) variation after 500-ml fluid load to diagnose responders (R). ΔEtCO2, ΔMAP, and ΔHR are the variation % of each hemodynamic parameter after a 500-ml fluid load
