An emergency resuscitation and defibrillation apparatus is provided by an endotracheal tube having a tracheal obturator and a second expandable cuff for sealing against the pharyngeal tissues to provide an alternate sealing means for respiratory fluids if the blind intubation is not successful. A laryngeal tube passes through this pharyngeal obturator for alternatively introducing respiratory fluids into the lungs through the larynx. The endotracheal tube may also be used as an esophageal obturator and inserted without the intubating guide means. Two internal electrode areas are provided; one of which may be in the oral region for contacting the tongue and one of which may be in the esophagus for contacting the esophageal wall. An internal conducting path is formed thereby for introducing electrical stimuli suitable for terminating cardiac fibrillation and other arrythmias. The endotracheal and laryngeal tubes may be individually accessed from outside the patient to ensure proper placement of the internal electrodes. |
