  1. Values are expressed as mean ± SD
  2. HR heart rate, BP, SBP systolic blood pressure, DBP diastolic blood pressure, MAP mean arterial pressure, CVP central venous pressure, CO cardiac output, SV stroke volume, SVV stroke volume variation, IJVV internal jugular venous variability, IVCV inferior vena cava variability
  3. T0 baseline, T1 after passive leg raising test, T2 after fluid expansion
  4. aP < 0.05 non-responders versus responders
  5. bP < 0.05 T1 versus T0
