Interventions/Control_1
We sustain anesthesia with concentration of 1MAC sevoflurane. Ventilator setting is pressure control ventilation with PEEP 5 cmH2O, tidal volume about 8 mL/kg, and adequate respiratory rate which maintains partial pressure of end tidal carbon dioxide 35-40 mmHg. Initial fresh gas flow is 4 L/min at an FIO2 0.25 in air. We measure respiratory status (tidal volume and partial pressure of end tidal and arterial carbon dioxide) as the control-1.
After measurement of the control-1, we alter FIO2 value to 0.3 in air and measure respiratory status as the air group 10 minutes or more after alteration.
Interventions/Control_2
After measurement of the air group, we alter FIO2 value to 0.25 again and measure respiratory status as the control-2 10 minutes or more after alteration.
After measurement of the control-2, we alter FIO2 value to 0.3 in nitrous oxide and measure respiratory status as the nitrous oxide group 10 minutes or more after alteration.
