The windpipe, or trachea, is a tube that connects the larynx to the bronchi of the lungs. Endotracheal tubes are hollow, flexible plastic tubes that are placed from the mouth to the trachea when a person is unable to breathe on his or her own. The endotracheal tubes are linked to a ventilator, which supplies enough oxygen to the patient. Endotracheal intubation is the process of inserting an endotracheal tube (EI). Endotracheal tubes come in a variety of styles, including cuffed, uncuffed, and reinforced.
An inflatable cuff surrounds a cuffed endotracheal tube, which is used to provide an airway through the trachea while also preventing aspiration of foreign materials such as saliva or vomitus into the bronchus.
