What Is a Double Lumen Catheter?

The double-lumen endotracheal tube is one of the endotracheal tubes used for bronchial intubation. Its characteristics are that the ventilation of the left and right common bronchial tubes can be temporarily separated, and anesthesia gas can be inhaled through both sides of the lumen, or anesthesia and ventilation can be performed only with a healthy side lumen, and the secretions can be removed at any time. ^[1]
