Ultrasound examination of the respiratory airway in the cervical region used by intensivists to evaluate the anatomical findings before the planned tracheostomy (especially the presence of vascular bundles below the site of the intended puncture and the presence of thyroid isthmus). The feasibility of the percutaneous dilatation technique is assessed which increases the safety of the procedure. Ultrasound can also be used for direct navigation of the puncture itself to optimize the cannula insertion site, i.e. level/height and centering in the trachea.
