If ASV isn't doing it for you you may want to check out Alternative approaches to treatment of Central Sleep Apnea

I don't know how to get my insurance to cover EERS titration since on paper the ASV is working for me just fine, but they don't measure CO2. I think my issue might be too much carbon dioxide due to shallow breathing as appose to central apneas. I've had a mask that I needed to cut a bigger hole in just to get more airflow. I'll give this a try though, maybe my current mask has too much airflow instead. One thing I don't understand is how they are suggesting to use a non ventilated mask with CPAP (in figure 1). What am I missing here?

You are missing the mechanics of what actually is the driving force behind the brain telling the body to breathe.
It's actually carbon dioxide blood levels...not oxygen as people assume.
The blood levels for carbon dioxide have to get to a certain point for the brain to wake up and say "oh, I gotta send the breathe stupid signal".
The non ventilated masks will speed up the increase in the blood levels of carbon dioxide to that point...because people end up re-breathing more of their own exhaled breaths which also contain carbon dioxide.
People shouldn't be trying this without careful monitoring and extra special care.

Hmmm, good question. My AHI was 0.0 but I did not feel well, so I took it upon myself to get a second opinion from another sleep specialist who specializes in complex sleep apnea. Apparently complaining that I still had symptoms even though my AHI said I was treated was enough for my insurance to pay for another sleep study.

They block the vent in the mask but add a separate vent using a Respironics Whisper Swivel II at the end of the CPAP hose before entering the EERS tubing.
