Arm && Interventions

Group	Intervention	Description
Paratracheal pressure	Mask ventilation	After the induction of anesthesia, paratracheal pressure is applied during mask ventilation.
No pressure	Mask ventilation	After the induction of anesthesia, no pressure is applied during mask ventilation.

Primary Outcome Measures

Name	Time	Method
Expiratory tidal volume	For 2 min of mask ventilation after the induction of anesthesia	Volume controlled mechanical ventilation is delivered during mask ventilation. Expiratory tidal volumes on the monitor screen are recorded during mask ventilation

Secondary Outcome Measures

Name	Time	Method
Inadequate tidal volume	For 2 min of mask ventilation after the induction of anesthesia	Incidence of tidal volume less than 150 mL is recorded.
Peak inspiratory pressure	For 2 min of mask ventilation after the induction of anesthesia	Peak inspiratory pressure on the screen is recorded during mask ventilation.
Incidence of hypoxia	For 2 min of mask ventilation after the induction of anesthesia	Occurrence of hypoxia (SpO2 \<90%) is recorded.
