oral airway, a curved tubular device of rubber, plastic, or metal placed in the oropharynx during general anesthesia and other situations in which the level of consciousness is impaired. Its purpose is to maintain free passage of air and keep the tongue from obstructing the trachea. The artificial airway is not removed until the patient begins to awaken and regains pharyngeal, cough, and swallowing reflexes. How to thank TFD for its existence?
