  1. Data are expressed as median with interquartile range (25th to 75th percentiles). * P < 0.05, ** P < 0.001, *** P < 0.0001 post VE vs pre VE; † P < 0.05 responders vs nonresponders.
  2. CI: cardiac index; CVP: central venous pressure; DAP: diastolic arterial pressure; HR: heart rate; MAP: mean arterial pressure; SAP: systolic arterial pressure; Svi: stroke volume index; TSVRi: total systemic vascular resistance index; VE: volume expansion.
