Bronchial intubation of the right or left mainstem bronchus can easily occur during infant endotracheal intubation because: Select one: a. b. C. d. e. The trachea is relatively short. The distance from the lips to the larynx is relatively short. The use of cuffed endotracheal tubes eliminates this issue. The mainstem bronchi are less angulated in their relation to the trachea. So little friction exists between the endotracheal tube and the wall of the trachea.
