Study Arms (3)

Intubation with the McGrath® MAC video laryngoscope

EXPERIMENTAL

Participants perform five intubation attempts using the airway manikin with the normal airway setting. After completing the normal airway session, the participants performed another five attempts with the neck immobilization setting using a neck collar.
