Low AHI, tired foggy mind

[Artanox]

Last night data with cervical collar and mouthtape, fixed pressure 14 and EPR 3
   

I have no idea of what to do next at this point

Those leaks are much better, you can definately see some correlation with those flow limits and leaks.

Now your leaks are under better control you could increase pressure to 15cm if it's comfortable, and see if it improves them?

Or you could try the other way, less pressure may control the leaks better and actually improve therapy and flow limits if the leaks are causing it?

1cm up or down would be interesting.

Maybe down would tell you more information quicker? If it leaks more at 13cm with 3 EPR, maybe you need more pressure. If it leaks less and flow limits are improved, then you can try even lower pressure.

Looks like you're getting very close anyway.

Those central apneas tells me that the pressure is too high right? so i will try to lower to 13 or 13,6 next and see.
I dont understand the correlation between the epr + mouthtape + cervical and no leaks.. the flow limit argument is one of the thing that i find poorly explained in the docs

[Apnea23]

That's what I understand, either too high pressure or EPR 3 high can cause centrals in some users.

Since your leaks were really good last night, maybe EP3 is helping with that, either because of exhale pressure or because pressure overall is less, so why not try 13cm and EPR 3 yes.

Out of interest how did you come to be using 13cm minimum originally, was that what you was prescribed?

Maybe all this time pressure has been too high, with too much pressure causing leaks, waxing/waning cycles etc as your system tries to balance the co2 etc. Who knows!

The experiments will tell you I guess.

Good luck. My last night on CPAP tonight even though it feels like I'm very close I'm not sure for me it will ever be good enough, had good news My ASV arrives tomorrow.

It's either going to work or fail and I'll be back adjusting settings again before the weekend. ?

Last night data with fixed 13 pressure and EPR 3 with mouthtape, fullface mask and cervical collar
I dont know what to say.. maybe i will try fixed 15 or APAP 13-15 or something i just dont understand those leaks, yesterday were fine

So what has worked so far for leaks and those short events, more fixed pressure and EPR I believe?

Sounds like it's time to bump things up. Lower pressure made your leaks worse. Jaw opening to breath, breaking the mask seal?

Why not 15 or 16 fixed if it's comfortable and you don't suffer aerophagia.

I just saw your original graphs again, wow what a difference in leaking compared to your 9cm minimum APAP settings.

Maybe could try 15-20 APAP, EPR 2 to try avoid centrals. ?

[Artanox]

In the original post the leaks were caused from a broken connector, since i fixed the connector yes the other day difference is very huge.
What bother me a lot are those CA, increasing the pressure will increase the CA so i really don't understand what my therapy should be, if my fullface mask is wrong and if i should use another machine like a bipap or something else, will talk with my doctor tomorrow.
I have to try different settings like fixed 15 EPR 3, 14-20 EPR3 15-20 EPR 3, 15-20 EPR 2 ecc..
really i have no idea if i'm in the good way or not lol
the first 0 of my life was with 14 fixed with cervical collar, without collar it gave me CA so something tell me that those high pressure are also wrong

[Apnea23]

Have you tried your original settings with the fixed connector?

[Artanox]

Those are all my settings since i had this new machine, i did 100 days on the prescribed settings and not all of them were with the broken connector.
What is making a difference i see is the cervical collar and the mouthtape so i should explore it more with various settings
like it makes no sense that mouthtape + collar at 14 give me 0 ahi and then same session mouthtape at 14 give me CA, (it's logged in the thread) so i dont understand 

If i'm correct i should first flatten the leak rate and flow limit and then try to reduce ahi, but still something seems off with the collar thing, i should try another night at 14 to see if i can score 0 again

Don't forget the main goal I think for us is to ensure good breathing through all sleep stages that doesn't descend in to waxing/waning causing mini events and arousals, ruining REM potentially.

My ADHD medication didn't work today after last night at 9cm fixed.

At 8.4 - 8.8cm fixed it did, and I had a great productive day. Today I could barely drive the car without having to very careful to concentrate.

Looking at my Oscar stats from last night it was the waxing/waning as always ruining a specific sleep stage, despite 0 AHI.

I always have 0-1 AHI but trashed REM sleep cycles.

The ASV better work or I'll be one P*ssed off guy tomorrow.
