RE: So I don't have OSA after using Cpap for 6 months
The only thing that strikes me is your N3 sleep being non-existent during the sleep test. If that changes as a result of CPAP use, that could be one benefit of continuing treatment. But, getting slow wave sleep (N3) is dependent on many factors. You may be able to adjust it with sleep hygiene, specifically in the bedtime snack, exercise choices, and mental stimulation categories.

RE: So I don't have OSA after using Cpap for 6 months
I was in the same boat...AHI of only 6, but RDI / RERA = 50+/hr. UARS diagnosis for me. Sure, CPAP isn't the perfect solution for UARS, but it can be very effective...I know I've seen the difference.

If you're feeling better during the day and sleeping better at night, then I personally don't see anything wrong with maintaining the CPAP therapy to combat the sleep disruptions associated with UARS...it's what I am doing and it has helped a lot.

YMMV, but if it was broke and seems better now, don't fix the fix Wink

While I have no major issues with the Cpap use, I would love to be able to not use it to just make bed a more pleasant place for my wife and I. It's not the end of the world I agree and it has helped, but I am a bit more to keen to looking for some solutions if it isn't OSA. We'll see. I'm going to explore a bit but continue my cpap.

From what I was told, N3 and N4 sleep are very similar and both represent deep restorative sleep. I currently have terrible sleep habits and tons of stimulation right before sleep and have been a lazy bum not going to gym for 6 months having gained 15lbs. I am probably a total of 20 lbs away from my goal weight (when I had more muscle)

we usually do not differentiate between N3 and N4 anymore (probably why there is no mention of N4 in your report). N3 = [N3 and N4].

Tongue Suck Technique for prevention of mouth breathing:
  • Place your tongue behind your front teeth on the roof of your mouth
  • let your tongue fill the space between the upper molars
  • gently suck to form a light vacuum
Practising during the day can help you to keep it at night

Sorry. How long were you in Stage N4?

When I read your notes about what the report said, I saw no mention of N4. Here is excerpt - "It was interesting to see that I spent 21 minutes in N1 sleep, 220 min in N2, 0 in N3 and 77.5 in REM. My AHI did jump up to 4.6 in REM."

RE: So I don't have OSA after using Cpap for 6 months
Don't forget that

  1. You've only got one night's sleep for each test. Even for people on fixed pressure CPAP, their nightly data may vary quite a bit from night to night.
  2. Your AHI number during the "bad" test was only 6
  3. Your home test did show AHI of 2.4
  4. Your home test did show an RDI of 10.9
  5. There's not an on/off function to apnea at 5 AHI. That's an artifact of insurance, regulation, and convention.


If you took the home sleep test again, it might well show you with an AHI of 6 or higher. It's one thing if your data shows an AHI of 40 on one test and nothing on another night.

RERA may be worse than you think. You may be "waking up" during each RERA. "Waking up" in terms of sleep stage, but you might not remember it. Think of how you'd feel if your alarm clock went off every 6 minutes all night long and you had to keep hitting the snooze button.

What does your AutoSet "think?" AHI, pressure range setting, does the pressure stay at the minimum setting, etc.?

BTW, I'm not saying you DO have apnea and need CPAP. I'm pointing out that the conclusion that you don't have apnea isn't really that clear cut.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
