Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Mcgrath Mac videolaryngoscope<br>Participants perform three intubation attempts using Mcgrath Mac videolaryngoscope in the manikin with the normal airway setting. Then the participants perform three intubation attempts using the manikin with difficult airway setting. | Other: Mcgrath Mac videolaryngoscope<br>* Participants perform three intubation attempts using Mcgrath Mac videolaryngoscope in the manikin with the normal airway and difficult airway settings.<br>|
| Experimental: C-MAC videolaryngoscope<br>Participants perform three intubation attempts using C-MAC videolaryngoscope in the manikin with the normal airway setting. Then the participants perform three intubation attempts using the manikin with difficult airway setting. | Other: C-MAC videolaryngoscope<br>* Participants perform three intubation attempts using C-MAC videolaryngoscope in the manikin with the normal airway and difficult airway settings.<br>|
| Active Comparator: Macintosh laryngoscope<br>Participants perform three intubation attempts using macintosh laryngoscope in the manikin with the normal airway setting. Then the participants perform three intubation attempts using the manikin with difficult airway setting. | Other: macintosh laryngoscope<br>* Participants perform three intubation attempts using macintosh laryngoscope in the manikin with the normal airway and difficult airway settings.<br>|
