Treatment and study plan

patient position

Other

After the induction of anesthesia, mask ventilation is performed in the supine and semi-sitting position in a cross-over, randomized order.

Primary outcomes

  1. Expiratory tidal volume

    Time frame: 1 minute after the induction of anesthesia

    Expiratory tidal volume is assessed during mask ventilation in the supine and semi-sitting positions.

Secondary outcomes

  1. Minute ventilation during mask ventilation in the supine and semi-sitting positions

    Time frame: 1 minute after anesthesia induction

    Minute ventilation is assessed during mask ventilation

  2. The incidence of inadequate mask ventilation or dead space ventilation.

    Time frame: during mask ventilation

    The incidence of inadequate mask ventilation or dead space ventilation is recorded.

  3. Peak inspiratory pressure

    Time frame: during mask ventilation

    Peak inspiratory pressure is recorded.
