An oral airway providing a patent airway to a patient, supplies oxygen to the patient and monitors expelled gases during endoscopic or intubating procedures. The oral airway includes a central lumen and two lateral breathing channels. A bracket at the proximal end of the oral airway functions to guide an oxygen supply line and an end tidal carbon dioxide monitoring line into the lateral breathing channels and to act as a barrier beyond which the airway cannot be inserted into the mouth of the patient. The airway has a straight main central lumen which serves as a guide and conduit to facilitate endoscope, bronchoscope, or fiber optic bronchoscope placement and manipulation. |
