ABSTRACT:
A respiratory mask provides improved sealing through the use of an intraoral mouthpiece with a large sealing area. A tubular extension, configured at one end to accept standard respiratory fittings, is the conduit for gas delivery to the intraoral mouthpiece. The respiratory mask may also include an intraoral oropharyngeal airway which flexes so that it can be inserted without the need for rotation or use of a tongue blade. The respiratory mask may also include an external shield to enhance sealing and provide a barrier of protection for the healthcare provider. The mask's design allows for a novel handgrip technique that allows a single healthcare provider to ventilate with enhanced sealing.
