Participant Flow

Participant milestones

Measure	Direct Laryngoscope teaching tracheal intubation using McGrath video laryngoscope as direct laryngoscope. Only trainer can see the monitor. direct laryngoscope: the trainee use McGrath video laryngoscope as direct laryngoscope the trainee is not allowed to watch the screen.	Video Laryngoscope teaching tracheal intubation using McGrath video laryngoscope using video function. Trainer and Trainee both see the monitor. video laryngoscope: the trainee use McGrath video laryngoscope both trainee and trainer can watch the screen.
