Treatment and study plan

Mask ventilation

Other

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

Primary outcomes

  1. Expiratory tidal volume

    Time frame: 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 outcomes

  1. Peak inspiratory pressure

    Time frame: For 2 min of mask ventilation after the induction of anesthesia

    Peak inspiratory pressure on the screen is recorded during mask ventilation.

  2. Inadequate tidal volume

    Time frame: For 2 min of mask ventilation after the induction of anesthesia

    Incidence of tidal volume less than 150 mL is recorded.

  3. Incidence of hypoxia

    Time frame: For 2 min of mask ventilation after the induction of anesthesia

    Occurrence of hypoxia (SpO2 <90%) is recorded.
