  1. Data are presented as mean ± standard deviation. PLR responders: cases with increase in pulse contour analysis-derived cardiac index ≥ 10% during passive leg raising, PLR non-responders: cases with increase in pulse contour analysis-derived cardiac index < 10% during passive leg raising
  2. TAMEAN time average mean velocity, PSV peak systolic velocity
  3. * p < 0.05 versus Baseline 1; # p < 0.05 versus Baseline 2; $ p < 0.05 versus Baseline 3
