 Inflation of the cuff in the esophagus allows a level of protection against aspiration of gastric content similar to that found in the laryngeal mask.The simplicity of placement is the main advantage of the Combitube over endotracheal intubation.When intubating with a traditional endotracheal tube, care must be taken to visually ensure that the tube has been placed in the trachea while the dual-lumen design of the Combitube allows for ventilation to proceed regardless of esophageal or tracheal placement.
