Changes in arterial blood gases, airway pressure, and ventilation frequency. a Changes in the P/F ratio were calculated by PaO2 analyzed by a blood gas analyzer and FIO2. b Changes in PaCO2 were analyzed by a blood gas analyzer. c, d Changes in peak airway pressure and ventilator frequency. Mean ± standard deviation. Peak airway pressure was significantly higher in the TV12 group. Ventilation frequency was greater in the TV6 group than in the TV12 group
