[CPAP] 1 month apap, now Flow Limits?

[Bwchase]

Very happy with my progress along the path to getting a good nights sleep! 
Thanks to all that have helped.
Had my first zero AHI 10 days or so back. Promptly changed to EPR of 3 from 2.n Thought it would help with mouth breathing and dry mouth.
AHI started creeping up. Went back to EPR, and again rewarded with zero AHI.
Look forward to tracking everyday with sleepyhead. Interesting to see where the OA happens and how the pressure increases.
My concern is where there are no events, and the pressure just keeps gradually going up to almost max programmed limit.
Started to research flow limits chart and what it means. Yes I have used the search function, and google and other searches.
As with other things sleep related, there are differing opinions on what the causes may be, and what significance these may bring.
What is your experience?

Perhaps it was caused by you changing sleep positions, or entering a different sleep stage.

For me, I can see my different sleep stages on my charts.

Every night, every 90 minutes or so I see an increase in my desperation for about 30 minutes. With that there is an increase in flow limitation and an increase in pressure to address the increased limitation.

You can see it at 1:20, 3:00, 4:15, 5:40.

I'm not concerned about it, infact I like to see it on my charts. When I see the repetitive sleep stage breathing patterns and the corresponding increase in pressure, I know the device is giving me only and exactly the pressure I need and it's been a good night.

It's when I don't see the patterned respiration rate, and volatile breathing patterns, that I've had a restless sleep.

I can often look at my breathing patterns, and know if I'm sleeping, awake or in that cyclic stage (I believe is REM). I also see a lot of false positives of CAs and OAs when I'm awake. 

I was awake at 7:20, and likely awake at 6:15.

Thank you for the information. This whole experience is like a winding journey back to health. More of a self driving thing!
Everyday is something new and interesting.

A flow limitation is a restriction in flow but insufficient reduction to score an apnoea flag but it is used by the machine as a sign that it needs to raise pressure, it could be positional or whatever. Increased EPR can be used to reduced flow limitations so I suggest leaving the EPR at 3. Your machine cleared the flow limitation and then dropped the pressure
