Abstract

A laryngeal mask airway (10) has a curved tubular guide (12) for insertion through the patient's mouth and oropharynx. After insertion of the guide (12), the beveled distal opening of the guide (12) abuts the laryngeal inlet (27), while the guide's proximal opening remains outside the patient's mouth. A laryngeal mask (30) surrounds the distal opening of the guide (12) to substantially seal the laryngeal inlet (27) about the distal opening of the guide (12). A ventilation port (16) adjacent to the proximal opening of the guide (12) supplies air/oxygen through the guide (12) into the patient's lungs. An endotracheal tube (40) can then be advanced along the length of guide (12) and through the patient's larynx (24) without interrupting ventilation.
