Comparison of responders (R) and non-responders (NR): two-tailed Wilcoxon’s rank test was performed between variables to compare before and after fluid expansion. Mann–Whitney U test was performed to compare responders to non-responders. Signs # for significant results comparing R and NR. Significant results comparing before and after fluid expansion are given by p value. Heart rate (HR), mean arterial pressure (MAP), diastolic arterial pressure (DAP), systolic arterial pressure (SAP), pulse pressure (PP), corrected systolic flow time (Ftc), cardiac index (CI), end-tidal carbon dioxide (EtCO2), and minute ventilation (MV). Data are expressed as median and [25th–75th]
