  1. Data are presented as means ± SD for normally distributed variables and as medians (25th to 75th centiles) for non-normally distributed variables. p values are those given by a two-way (time, treatment) analysis of covariance, the analysis being adjusted on baseline values (mixed model) for normally distributed variables or a non-parametric repeated-measures analysis, and also adjusted on baseline values (mixed model), performed on ranked data, for non-normally distributed variables. CO, cardiac output; D, dopexamine; DO2, oxygen delivery; E, epinephrine; GMBF, gastric mucosal blood flow; HR, heart rate; MAP, mean arterial pressure; MPAP, mean pulmonary arterial pressure; N, norepinephrine; PCWP, pulmonary capillary wedge pressure; pu, perfusion units; PVR, pulmonary vascular resistances; RAP, right atrial pressure; SV, stroke volume; SVR, systemic vascular resistances; VO2, oxygen consumption.
