Literature shows that anaesthetists have a low success-rate when trying to access the airway percutaneously in case of failed ventilation and intubation.
The study will investigate anaesthetists ability to locate the trachea and the thyroid cartilage and the cricoid cartilage in patients, using different methods including application of ultrasonography.

The researchers will investigate anaesthetists ability to locate the trachea and the thyroid cartilage and the cricoid cartilage of a healthy subject with different methods including application of ultrasonography.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Cranial horizontal | Active Comparator | identification of the airway by from the cranial end. Marking of the airway, including the cricothyroid membrane, on the skin, by starting the examination from the cranial end at the level of the thyroid catilage , horizontally and thereafter moving caudally |
|
| caudal longitudinal | Active Comparator | identification of the airway from the distal end. Marking of the airway, including the cricothyroid membrane, on the skin, by starting the examination caudally, and then moving cranially |
