Another modification of the EOA is the tracheoesophageal airway (TEA) ( Fig 14.-5.ii). It has a standard endotracheal tube (ETT) with two openings, one for the ETT
and the other for oropharyngeal ventilation. It is designed to function equally well if inserted into the trachea or the esophagus. Tracheal intubation is facilitated by using cricoid pressure and extending the neck. While the tube is in the trachea, the cuff is inflated and the patient is ventilated normally. While the tube is in the esophagus, the patient is ventilated through the mask and the ETT allows for gastric venting or decompression.
