Interventions/Control_1
Comfirm the recovery of the train-of-four ratio not less than 0.9 after intubation.
Sustain anesthesia with concentration of 1MAC sevoflurrane.
Ventilator setting is pressure control ventilation with PEEP 5 cmH2O, tidal volume of 8 mL/kg, and adequate respiratory rate which maintains end tidal carbon dioxide 35-40 mmHg. Initial fresh gas flow is 4 L/min at an FIO2 0.25 in air.
After measurement of control, we alter FIO2 value to 0.3 in air in non-administration of nitrous oxide group, and measure tidal volume every one minute for 5 minutes.
Interventions/Control_2
After measurement of control, we alter FIO2 value to 0.3 in nitrous oxide in administration of nitrous oxide(70%) group, and measure tidal volume every one minute for 5 minutes.
Interventions/Control_3
After measurement of control, we alter FIO2 value to 0.65 in nitrous oxide in administration of nitrous oxide(35%) group, and measure tidal volume every one minute for 5 minutes.
