Data are expressed as mean values ± standard deviation. AUC, area under the curve; AVP, arginine vasopressin; CI, cardiac index; DO2I, systemic oxygen transport index; MAP, mean arterial pressure; NE, norepinephrine; ODS, oscillation of the Doppler signal; RH, reactive hyperaemia; SvO2, mixed venous oxygen saturation; VO2I, systemic oxygen consumption index. *significant difference over time; †, significant difference between groups; ‡, significant difference at baseline between groups; §, corrected for baseline differences. | ||||
