Table 2.
Hemodynamic measurements at baseline (pressure control ventilation, pre-apnea), zero (end of apnea) and then one, two, five, and ten minutes after initiation of ventilation with Ventrain.

Data are presented as median [interquartile range]
CO = cardiac output; HR = heart rate; MAP = mean arterial blood pressure; PAP = pulmonary artery pressure; SvO2 = mixed venous oxygen saturation; *P < 0.05 vs baseline, # P < 0.05 1 min vs 0 min
