I expect your results will be inconsistent and that central events will eventually return. Based on your sleep study, you should be failing at your use of CPAP, and yet, you're doing great so far. If CA events return, you will ultimately need a more sophisticated machine called an adaptive servo ventilator (ASV). On the other hand, you may be one of the rare cases that resolves sleep disordered breathing using CPAP. These are remarkable and unusual results. For the time being, there is nothing I would change about your therapy, but I will be surprised if it actually works in the long run in its current form.
So, Sleeprider, I have been struggling for about the last 12-18 months. I have had every blood test they can throw at me and they have all come back normal. I had mentioned to my doctor that I felt it might be my sleep and, after much nagging, she finally agreed to refer me for another sleep study. My goal was to have the study done as I used my machine, so they gave me a home sleep test (HST). The HST essentially showed that my apnea was under control. I think it came back with an AHI of 1. I finally managed to get a sit-down with the sleep doctor, so I took my MacBook in with my data loaded into OSCAR. As I explained everything to him, he said that I have the wrong machine if I am struggling with central events and agreed that I should be reevaluated. He was perplexed that I have not had a follow-up in the three years I have been using my CPAP. He also changed my prescription from a fixed 14cm in CPAP mode to 6cm to 12cm in APAP mode. Last night was my first night with it, so we'll see how well it works. I have my sleep study next Sunday night to evaluate me without a machine to see if I am still having a moderate number of central events.

sheepless, my CA has continued. Over the past week, it has been horrible and I don't know why. My Cheyenne-Stokes episodes have been crazy over the past week as well. I really expect the doctor to recommend an ASV after my sleep study, but we will see what happens. My fear is that I go in and have a good night (I have those on my machine from time to time) and they way, "Well, you seem to be fine." Time will tell.
