Course of mean arterial pressure (MAP) and respiratory characteristics after mechanical ventilation.
MAP was similar in all experimental groups. Plateau pressure after 3 h of mechanical ventilation was higher in animals receiving 7 cmH2O PEEP (PEEP-7). Respiratory system compliance (Crs), pH, and PaO2/FiO2 were lower and PaCO2 was higher in PEEP-7 than in those receiving 2 cmH2O PEEP (PEEP-2). Bars represent means ± SEM. ∗∗P < 0.05 PEEP-7 vs. PEEP-2.
