Anatomical relationships of complications associated with percutaneous dilatational tracheostomy. Establishing a safety margin for puncture and dilation is difficult based only on anatomical references and bronchoscopy due to the number of adjacent structures and their anatomical variations (Created with BioRender.com)

A Step 1: ultrasound exploration with linear transducer, absence of high-riding innominate artery. B Step 1 ultrasound exploration with sector transducer, innominate artery is identified with color Doppler. C Step 2: pretracheal structures identified with color Doppler along the transversal axis of the airway. D Step 3: Lateral margins are defined measuring the distance from the midpoint of the trachea to the lateral margin of the vessel. E The safety area is delimited (Created with BioRender.com)

A Step 7: Endotracheal tube is visualized as two parallel hyperechoic line beyond the trachea. B Step 7: Real-time visualization of tube displacement. C Step 7: Distal end of the tube above cricoid cartilage. D Step 8: Air flush test
