ABSTRACT:
An esophago-pharyngeal airway having at least one inflatable cuff for sealing the nasal passage by urging the soft palate against the posterior nasopharyngeal wall and sometimes another inflatable cuff engageable with the wall of the esophagus to prevent ventilation of the stomach and possible aspiration of the stomach's contents depending upon the selected use. Either or both of the cuffs may be continuously inflated during use of the airway or may automatically inflate and deflate with each respiratory cycle to insure non-traumatic extubation when a tracheal tube is substituted for the esophago-pharyngeal airway. An air tube extends through one of the cuffs and a gastro-esophagus tube extends through both of the cuffs. In one form of the device, the lower cuff is adapted to be positioned in the esophagus between the heart and sternum and is provided with means not only for electronically monitoring heart operation but also for defibrillating the heart when the device is in place for performing artificial respiration.
