Straining to inhale

[SarcasticDave94]

OK copy on the CA aspect. So I'll call that a handful were present in the diagnostic.

This will probably sound generic, but experiment with what others are suggesting, find a sweet spot middle ground that avoid CA while allowing comfortable therapy that treats the rest of the events. I specifically say avoid, because with anything other than a specific CA treatment device, avoiding is the best you can get.

If this is an APAP (not sure if all S11 are APAP like all S10 are not all APAP) why fix the pressure at 8? Sure it is more than 6 which can't help much (e.g. not so easy to inhale), but it is an intelligent machine which can deliver a more optimal experience than one value. 

CPAP is fine and I use it when I travel so I have no choice (set at the mean of OSCAR values from APAP), but I'd suggest setting it from 7-12 (not that the upper number matters if it won't be reached) and EPR of 3. 

Oh, and turn ramping off. I don't understand the benefit of not getting near enough pressure for half an hour vs. getting it PDQ if you will get there anyway.  I found it very hard to wait for proper pressure so I go from zero to the initial level of 7 on APAP in about 4 seconds. You can feel it when it becomes easy to breathe.
