Outcomes

Primary Outcomes

Time to intubation

time from insertion of the blade to the first manual ventilation of the manikin´s lungs. If time of intubation is over than 60 seconds, attempt was recognized as failure.

Time frame: 1 day

Secondary Outcomes

Success of intubation

effectiveness of the first, second and third intubation attempts and overall effectiveness of intubation by participants using four intubation devices. If the examinee failed at all attempts, the case was excluded from the time calculations.

Time frame: 1 day

Ease of Use

To access subjective opinions about the difficulty of the each intubation method, participants were asked to give a rating on a visual analogue scale (VAS) with a score from 1 (extremely easy) to 10 (extremely difficult).

Time frame: 1 day

POGO score

The POGO score describes how much glottic opening is visible. A POGO score of 100% indicates visualization of the entire glottic opening from the anterior commissure of the vocal cords to the interarytenoid notch. A POGO score of 0% corresponds with no visualization of laryngeal structures.

Time frame: 1 day

Cormack-Lehane grading

self-reported percentage the vocal cord visualization using the Cormack-Lehane grading (grade 1-4)

Time frame: 1 day

dental compression

pressure applied on the upper teeth (n=none, mild=1, moderate=2, severe=3)

Time frame: 1 day
