Re the sensors Sullivan was talking about.
I will happily bet that they are far more sophisticated today that in 2001/2002 (which has to be more or less the timeframe Sulling was referring to).
In fact the VPAP Adapt SV would probably not work very well at all if it weren't for significant advances in both types of sensor. IIRC Honeywell was commissioned to produce what Resmed claimed (somewhere) were the most advanced sensors used in any cpap machine.

Now here is a good debating topic - AHI useful or useless ?
Although im really new at this it seems to me that AHI is not very useful in alot of cases, like mine for instance my sleep study revealed an AHI of 8 which gives me a lot of memory loss that ive been having and the fatigue. That might be very low for some people, but it has a much greater affect on me. If think thats what Dr. S was meaning by his article.
