Abstract
GLOSSOPHARYNGEAL breathing, first described by Dail1 in 1951, is a technic for ventilating the lungs that does not require the use of the muscles of respiration. Instead, the muscles of the mouth and pharynx are utilized to force air into the lungs under positive pressure. A volume of air averaging 60 ml. is trapped in the pharynx when the mouth and nasopharynx are closed. The air is then forced into the trachea by the constricting action of the pharyngeal muscles and upward displacement of the tongue. The trapped air is held in the trachea and lungs by closing of the . . .
