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
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
