Based on a 2007 sleep study, AHI of 13.9/hr with a REM AHI of 51.2/hr, oxgyen desaturations to 80%. I've noticed the apneas only occur when I have had my mouth open.

Is there a chin strap that would work with the Respironics full face mask? I'm having problems with my mouth opening during sleep that have resulted in apneas.
