Brief summary

Detailed description

test persons, anaesthesiologists will identify the cricothyroid membrane on a silicone model of the neck with either palpation or ultrasonography. The larynx-model is deviated to one of the sides to simulate a patient with neck pathology. The test persons are randomised to use other palpation or ultrasonography. Al attempts are video-taped

Design outcomes

Primary

Measure	Time frame	Description
Correct identification of the cricothyroid membrane within a minute	1 minute	The fraction of identifications of the location of the cricothyroid membrane made by the participants, that is actually correct. ie the succesrate of correct identification.

Secondary

Measure	Time frame	Description
Time taken to identification of the estimated location of the cricothyroid membrane.	up to 3 minutes	The time elapsing from the participants initiate their attempt at identificating the cricothyroid membrane until they have finished their attempt at identifying the cricothyroid membrane.
