Absolutely. The people who wrote the algorithms are attempting to analyse people's breathing patterns, and to conclude, from that analysis, what the present breath means in the context of what preceded it. Now, the analysis may be spot on for part of the population, and way off for another part - some machines are better for some people.
I doubt knowledge is developed enough for doctors to be able to figure out the criteria.

Hi O,
I agree wholeheartedly! I don't believe that sleep apnea is a single condition - or at the very least it has many variations. I'm not sure how well a single machine could adequately address all of the variations without being the size of a Sherman tank (perhaps someday...)
Good for DeVilbiss for listening to users and trying to improve their technology and for working with Johnny Goodman on setting up this challenge. I don't agree with folks who complain that it's not a scientifically designed trial. I'm involved in many of many of those and there would be huge (and expensive) issues in setting up a clinical trial that would be meaningful for a product that is so prone to individual likes and dislikes.
For the time being, I'll stick with my Sandman Auto because of my runaway centrals which the Sandman handles beautifully. I have mine on Auto mode and now that I've found the best "bottom" pressure, it rarely varies much. I use a range of 10-20 and most nights it sticks solidly to 10 with an AHI <1. When I tried a range of 9-20, I'd typically run an average pressure of 10.2 - 10.5 with an AHI between 1 and 3. So, in this very unscientific experiment, it looks like upping my bottom pressure to my "sweet spot" is avoiding the time lag to raise pressure to resolve apneas and improving my therapy.
So, for those of you who had a very flat pressure line with the Intellipap, is it possible that with no pressure relief and the bottom pressure set accurately, that it makes sense?
As far as exhale relief - I used A-flex and C-flex on my Respironics and thought I needed it. However I haven't missed it on the Sandman at all. Haven't used the ramp feature either - but if I ever had problems with exhale relief, I'd probably try ramp first to see if I could fall asleep (and then stay asleep) without it.
