In theory, the nasal-type CPAP headsets assume that the 5-15psi or so of pressure will not break the seal of your lips… Now, we all know that the weak seal of the lips could never hold back that much pressure, correct? Not a problem! Coincidentally, with the pressure going in on the nasal side of the soft palate, this creates a vacuum in the oropharynx, which brings the tongue up and back to the rook of the mouth and sides of the cheeks. So, now the pressure is ultimately being held back by the seal of the tongue against the insides of the mouth.
Now, my experience with the nasal headset is that, eventually, the pressure seeps around the sides of my tongue, blows it back down into its resting place, and SNAFU, the pressure releases from my mouth, there is a loud rushing sound of air, and I wake up, interrupting my sleep. This happens even when my jaw and teeth are properly clenched with a chin strap!!! :eek: THis happens time and time again.
Since then, I am trying to adjust to my new facial mask, which is a royal pain in the ass and bridge of my nose. But, is this nasal headset problem a common problem? My tongue is just relatively too small to occlude the pressure, how can this be happening!!!??? How does this not happen to everyone?
