Outcome Measures

Primary Outcomes (1)

  • Expiratory tidal volume

    Volume controlled mechanical ventilation is delivered during mask ventilation. Expiratory tidal volumes on the monitor screen are recorded during mask ventilation

    For 2 min of mask ventilation after the induction of anesthesia

Secondary Outcomes (3)

  • Peak inspiratory pressure

    For 2 min of mask ventilation after the induction of anesthesia

  • Inadequate tidal volume

    For 2 min of mask ventilation after the induction of anesthesia

  • Incidence of hypoxia

    For 2 min of mask ventilation after the induction of anesthesia

Study Arms (2)

Paratracheal pressure

EXPERIMENTAL

After the induction of anesthesia, paratracheal pressure is applied during mask ventilation.

Other: Mask ventilation

No pressure

ACTIVE COMPARATOR

After the induction of anesthesia, no pressure is applied during mask ventilation.

Other: Mask ventilation

Interventions

Mask ventilation is performed under paratracheal pressure or no pressure in a randomized, crossover manner.
