Abstract

A mouth mask includes a unitary member having an inner wall portion and an outer wall portion. The unitary member is adapted to seal about the lips of a patient with the perimeter defined by the intersection of the inner and outer wall portions resting on the perioral area overlying the maxilla and mandible. The mouth mask also includes an opening extending through the unitary member for connecting oxygen and ventilating through a mouthpiece or pharyngeal airway inserted through the opening in the mouth mask. The opening is adapted to receive an airway having a proximal end disposed externally of the patient and a distal end disposed internally of the patient in the region of the lower pharynx. Additionally, the mouth mask may selectively be provided with a nostril occluding balloon or cushion to pneumatically seal and block the nostrils of the patient.
