 The combitube is designed with two lumens including a pharyngeal lumen blind distal end and a blue proximal end which allows communication with the airway via holes positioned just above the lower pharynx and a tracheal lumen clear, short proximal portion and open distal portion. The device also has two balloons to allow for adequate ventilation and oxygenation while minimizing the risk of aspiration. The oropharyngeal balloon is located above the pharyngeal perforations and when inflated 85 - 100 mL of air seals the oral and nasal cavity. The distal balloon is positioned just above the distal tracheal lumen opening and will seal either the esophagus or the trachea depending upon the positioning when inflated.
