A device and method for tilting an unconscious patient's head rearward and lifting his chin to prevent an airway obstruction from developing during intravenous anesthesia when the patient is unconscious but still breathing spontaneously during surgery. The invention is comprised of a neck support for positioning a patient's head in a face-up, supine position and provide a fulcrum for tilting the head rearward on a surface, such as the top surface of an operating table or hospital cart. An extensible swing-arm mounted on an end portion of the neck support carries a cross-arm and a chin support. The swing-arm is rotated, the chin support is engaged with the patient's chin and the patient's head is extended and chin is lifted by an anesthetist provider. The swing-arm and chin cup are mechanically fixed to release the anesthetist provider from the task of maintaining the rearward tilt of the head and chin lifted positions.
