Sounds good. I think probable your current setting are doing the basic job, as events are well controlled. Hypopneas are of less importanve than obstructives.(See video link at bottom of this page).
My guess would be if leaks can be controlled, many of these events should disappear. Then the settings can be perfected.
Note - with tape, make sure it is sufficiently long enough hotizontally to cover the corners of your mouth, which are weak spots. The length I use is 13 cms.
You won't know until you try..
See lankylefty video here which is quite informative.
If you wouldn't mind looking at this data from last night and advise me that would be fantastic.
I have the large leaks sorted now and just trying to dial it in as best I can now.
The previous few days look very similar to these screenshots, I can however see that the more I bump pressure up little by little the higher the leak rate (not large leaks) gets.
In your last set of graphs, your large leaks have disappeared. The general leak rate (95%) of 13.2 was well below the Resmed limit of 24/l per minute. So yes, good progress.
I guess you are using mouth tape now. One extra tip I forgot, before affixing, curl your lips inwards so they are more or less invisible, then apply tape. Result, a much better seal (hopefully). Try it.
I see your EPR is zero now, any particular reason? Your 95% flow limitation of 0,21 is much too high.
Suggest to go back to 3.
Overall your events are quite well controlled, with just one central apnea of 14 seconds. The remainder of the events are just hypopnea, less disruptive, but would be good to try and reduce these a bit.
To do this you could start to increase your pressure incrementally, say in steps of 0.2 every few days to see what happens. Having a better seal as above, the pressure increases should not be disruptive.
I turned epr off as with it on 3 I had alot of central apneas. In an effort to reduce these I switched it off completely. The central apneas disappeared instantly.
Maybe go to mid point EPR. It's a balancing act, on one side you can reduce/eliminate centrals, but price to be paid can be increased centrals. It depends on the other side of the coin, if higher flow limitations bother you.
Drilling down a bit deeper, your centrals could be "machine emergent", and will dissapate over time, of they could be caused by C02 "flushing". With deminished C02, the brain can be tricked in not needing to breathe to clear it away.
It's due to the rapid change from inspirational pressure to exhatational pressure.
In your case, it does look like C02 flushing, so I think you made the right call.
This leaves the issue of flow limitations.
I have found that just increasing pressure does help. So hopefully as you deal with the hypopnea, a nice side effect may be flow limitations improve also.
So, a few variables for you to juggle with.
The bottom line is always how you feel. You are best and only judge.
