RT2 Sagittal diameter of trachea in the newborn [radiography]
Measurements of the trachea are useful for detection of tracheal abnormalities and in problems with endotracheal intubation, endoscopy and tracheostomy. Tracheal dimensions undergo considerable changes parallel with changes in intraluminal pressure and respiratory phase, as well as body position. The data presented are therefore only valid for the given examination circumstances (see below).
