Respiratory 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]
EEP = end-expiratory pressure; PaCO2 = arterial partial pressure of carbon dioxide; PaO2 = arterial partial pressure of oxygen; PIP = peak inspiratory pressure; SaO2 = arterial oxygen saturation; *P < 0.05 vs baseline, # P < 0.05 1 min vs 0 min
