NO
To investigate the effect of nitrous oxide on tidal volume and partial pressure of end tidal and arterial carbon dioxide
Pharmacodynamics
Changes in the tidal volume and partial pressure of end tidal and arterial carbon dioxide from the control
1. Changes in the lung compliance
2. Changes in the airway resistance
3. Body temperature
4. Cahanges in the end tidal sevoflurane concentration

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.
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.
