nasal mask, mouth breathing and CA
#1
Hello, I am asking for some help on this, and I am new to the forum so if its posted already please forgive me.

I use a Respironics system one APAP and nasal mask. 3 years now
Can using a nasal mask and having your mouth open and air leak out during sleep give the machine and also Sleepyhead software the wrong info and make it look like clear airway apnea?
I have noticed that when i wake up on days that I can tell I have had mouth leaks, (dry mouth and sore throat) I feel terrible as if I didnt even use the machine at all but the software says i had an AHI of only .68 to 1.37, it does however show more CA events compared to my normal obstrucive aireway apneas.

I essentially am having the same problem with mouth leaks. I wouldn't say it's unmanageable at this point. Having the heated tube on my APAP machine has helped decrease the problem somewhat. Some nights are better than others. They say going to a full face mask would be the next step after everything I've tried. You might want to look into doing the same.

Hi torgoth,
WELCOME! to the forum.!
If you are unable to get the mask you are using niw to work well for you, you might consider trying another mask; this is the hardest part of the therapy.
Hang in there for more suggestions and much success to you with your CPAP therapy and finding a mask that will work.

I don't see how having a mouth leak could increase centrals; however, it will most definitely decrease the efficacy of your treatment, which would explain the crap feeling in the morning. Have you tried a chin strap to help keep the mouth shut? Or have you tried a ffm?

True centrals? No, I don't think so. But an unidentified clear airway event, which is what Sleepyhead is reporting? Yeah, could be.

Time to see about Mr. Chinstrap.

torgoth,
If you have a high leak rate, you can't count on your machine to record apneas correctly. Do whatever is needed to tackle those leaks, either use a chin strap,
or try a different mask.
Some even go to a full face mask to tackle the problem.
