Combitube

From Wikipedia, the free encyclopedia

The Combitube (combitube.org) is a device designed to facilitate the blind intubation of a patient.

It consists of a cuffed double lumen tube with one blind end. Inflation of the cuff allows the device to function as an endotracheal tube and closes off the (o)esophagus, allowing ventilation and preventing reflux of gastric contents.

While it has been suggested as an option by the American Heart Association and European Resuscitation Council, it is seldom used. The main alternatives are the laryngeal mask airway (LMA) and the endotracheal tube.
