Variable dwell time between breaths

[Pugsy]

Any experience with going to BiPAP to clear flow limitations/snoring without aerophagia?

Not really any experience. I can count on one hand (in nearly 15 years on cpap) the number of times I have had any issues with aerophagia.
I never have had any real issues with FLs or even snores once on cpap.

I am on a bilevel machine but that is because I got a chance to try one and found I really liked PS of 4 (over PS of 3) even though it was never a critical need for me. I just like it better. I can use an AutoSet and EPR at 3 and do well with it but I just really like how PS of 4 feels.
Much more "natural" breathing feeling to me anyway.

I rely mainly on how I sleep and feel and not so much as any numbers or graphs.
Sleep is my primary goal because without it then the nice pretty graphs don't mean much.

Got more blood work on Friday. All normal for Thyroid, Testosterone, Vitamin D. The only slightly unusual numbers (but still normal) were hemoglobin and CO2. My 02 doesn't really seem to drop much at night, but maybe the high CO2 is messing up my breathing while asleep.
