简要总结
The purpose of this study is to investigate the changes of the oropharyngeal leak pressure of the air-Q self-pressurizing masked laryngeal airway in the different head and neck positions. Moreover, the adequacy of ventilation will be assessed in the different head and neck positions.

结局指标
主要结局
Oropharyngeal leak pressure
时间窗: Within 5 minutes after the insertion of the air-q self-pressurizing masked laryngeal airway
The oropharyngeal leak pressure was measured by closing the expiratory valve of the circle system at fixed O2 flow 3L/min and 40 cmH2O
次要结局
- Peak airway pressure(Within 5 minutes after the insertion of the air-q self-pressurizing masked laryngeal airway)
- Fiberoptic bronchoscope grade(Within 5 minutes after the insertion of the air-q self-pressurizing masked laryngeal airway)
