An adjustable oral airway device, comprising:

• a bite block;
• the bite block having an opening extending therethrough, and having a longitudinal dimension along the opening;
• a tongue deflector extending within the opening through the bite block;
• the tongue deflector being slideably engaged within the bite block;
• the tongue deflector being a strip of material and comprising a straight region and a curved region;
• the straight region being at least as long as the longitudinal dimension of the bite block;
• and
• the bite block and tongue deflector cooperatively defining at least one locking mechanism, the locking mechanism defining a plurality of different predefined positions for retaining the tongue deflector within the bite block, wherein the locking mechanism includes two or more cavities in a side of the bite block portion, and includes at least one deflectable protuberance along a side of the tongue deflector portion;
• the deflectable protuberance being configured to seat within the cavities to releasably retain the tongue deflector portion in said one of the predefined positions;
• wherein the locking mechanism further includes opposing cavities in another side of the bite block opposing the one side, the tongue deflector portion further including another deflectable protuberance opposing the one deflectable protuberance, the other protuberance configured to seat within the opposing cavities to releasably retain the tongue deflector portion in said one of the predefined positions.
