Double-lumen endobronchial tube

A Double-lumen endobronchial tube (pronunciation: duh-buhl loo-muhn en-doh-bron-kee-uhl toob) is a specialized medical device used primarily in thoracic surgery or for ventilation of one lung.

Etymology

The term "Double-lumen endobronchial tube" is derived from the Latin words "duplicis" meaning double, "lumen" meaning light, and "endo-bronchialis" referring to the inside of the bronchial tubes.

Description

A Double-lumen endobronchial tube is a type of endotracheal tube that is designed with two separate lumens or channels. One lumen seals off the right or left main bronchus to allow the lungs to be ventilated independently. This is particularly useful in thoracic surgery where one lung can be collapsed to provide a better view and access to the surgical field.
