Other than keep your mouth shut, on your own or with a chin strap, or trying to minimize mask leaks?
I have seen some mention of lowering or turning off the exhale relief feature. How does that work?
If that's so, what is more important, comfort or lowering the AI and HI level?
What if you have a low AHI level, mine is around 2.1? Is it worth messing around with this stuff?
Turning off EPR can reduce central apneas for people who experience them.
With an AHI if 2.1, that falls into the category of: "If it ain't broke, don't fix it."
Seriously, at 2.1, you're doing just fine.
INFORMATION ON APNEA BOARD FORUMS OR ON APNEABOARD.COM SHOULD NOT BE CONSIDERED AS MEDICAL ADVICE. ALWAYS SEEK THE ADVICE OF A PHYSICIAN BEFORE SEEKING TREATMENT FOR MEDICAL CONDITIONS, INCLUDING SLEEP APNEA. INFORMATION POSTED ON THE APNEA BOARD WEB SITE AND FORUMS ARE PERSONAL OPINION ONLY AND NOT NECESSARILY A STATEMENT OF FACT.
Just a few thoughts: First, I would say comfort is more important because if you aren't comfortable with your therapy, you won't want to continue it.
Second, I know getting your AHI down below 5 is also important, but how you feel can play a part in this whole thing as well.
Third, You ask if it was worth keeping up with this stuff, yes, it's worth knowing what is going on with your sleep.
Hang in there for other ideas.
