Anybody have any experience or suggestions for this.
Hi Norm, after six years of nasal pillows, chin strap and mouth taping, I have resorted to a FFM to remedy mouth leaks, or to be more exact, therapy air exhausting via mouth. I found with APAP the air pressure would increase enough to blow the tape away allowing the air to gush out drying out my mouth and waking me. The FFM I found, didn't solve the issue completely but is way better. With my FFM I use a chin strap. I still have leaks, but little or no dry mouth.
There's a lot on this forum about hydration & relative humidity & their relationship to dry mouth. When we go to bed, under the covers, RH drops way down below the ambient. Surprising but true. This contributes to bodily dehydration with accompanying dry mouth. However body temperature (heat) remains constant all night. Below is a graph from my data logger showing this. Hope this helps.

Wow Geoff, that is amazing to me. Completely counter to what I would have expected. Thanks for sharing that. I still have not figured out what makes the reduction in RH happen.

Best Regards,

This result is not an aberration either. I have done this experiment several times and the results are more or less the same. I think it's possible that when we sleep under covers, we isolate our bodies from the ambient RH and establish a small eco system of our own. Since we are at rest, we don't perspire unless overheating, (too many blankets) so I'm guessing that's the reason. Based on this assumption, I would say that if RH doesn't drop during sleep, it's possible the sleeper is overheating. My conviction is, overheating is a precursor to SA & that's what I was trying to prove with this experiment.
