Description of intervention(s) / exposure
Forces applied during laryngoscopy will be measured by a modified laryngoscope designed by one of the investigators- not commercially available. Participants will perform laryngoscopy on the simulator centre manikins under standard conditions and under different degrees of difficulty, (tongue swelling, tongue swelling with cervical stabilization). 3 laryngoscopies will occur for each setting. The force will be measured for each. Participants will have varying experience of intubation.
