Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Standardised flexible airway scope guided intubation technique via an i-gel supraglottic airway device (SGA), placed orally by an emergency physician (EP) with preliminary training consisting of a 60 minute training session on scope familiarisation, practice on an airway mannequin, and then on a cadaver.

It is anticipated that the intubation technique will be completed within 2 minutes.
During the procedure the process will be supervised by an experienced emergency physician, familiar with the technique, who is able to offer advice on the procedure.

Regarding the 'wash out' period:
The individual physician will undertake both the intervention and comparator techniques on the cadavers as part of a randomised sequence of experiments. As such there will be no 'wash out'; In theory the random sequence could mean, for example, 'physician 2' to perform FAS then HAVL one immediately after the other on the same cadaver.

Treatment: Devices
Comparator / control treatment
Standardised hyperangulated video laryngoscope (HAVL) guided intubation technique using a endotracheal tube (ETT) mounted on a stylet.

It is anticipated that the intubation technique will be completed within 2 minutes.
During the procedure the process will be supervised by an experienced emergency physician, familiar with the technique, who is able to offer advice on the procedure.
