 The ETC is a disposable double-lumen tube that combines the features of a conventional endotracheal tube with those of an esophageal obturator airway. It is appropriate for prehospital, intraoperative, and emergency use and is especially useful for patients in whom direct visualization of the vocal cords is not possible, patients with massive airway bleeding or regurgitation, limited access to the airway, and patients in whom neck movement is contraindicated. Ventilation with the ETC is possible with either tracheal or esophageal intubation, as its distal cuff seals off the esophagus to prevent aspiration of gastric contents. The ETC has a 6.9 incidence of placement failure and a failed ventilation rate of 21.1.
