Auto machines also use other factors to determine when pressure needs to be increased. I'm not sure of all of them, but flow limitation (as Sleepster said) might be one. I know that "Snore" is one that is used with ResMed machines (probably other brands too). The snoring doesn't even have to be loud enough to hear. I think they determine what they call "snore" based on waveform patterns. I never snore enough that anybody would be able to hear it now that I use PAP; but, I get some pressure increases that do not correspond to apneas or hypopneas and most of the time I can look at the "Snore Index" graph and see that the pressure increase seems to be in response to slight snoring. I guess they (the machine designers) figure that if they can keep the snoring from escalating, then they can prevent the obstruction from getting worse and causing hypopneas and apneas.

You might be able to get the DME to take the Escape Auto back and give you an AutoSet (they might want to charge you a little extra for the exchange). If your doctor is worth his/her salt, s/he might be willing to help by agreeing you need the data, which includes things like "Flow Limitation" and "Snore Index" graphs, to monitor and optimize therapy. If so, s/he could write you a "dispense as written" prescription for an AutoSet.
I'm not sure about all of this because when the lousy DME foisted an Escape Auto on me it was just a rental and they had to take it back. The H5i humidifier was a lump sum purchase though (and outrageously priced) so I had to keep it; but that's not a problem because all S9s use the same humidifier.
I would strongly encourage you to be vigilant in trying to get the upgrade to the data capable machine. Hopefully you can get your doctor to advocate for you and you might even get lucky like I did and find someone helpful at your insurance company. Less of a chance; but, you might be able to get the DME to consider putting your health above their profit margin (don't hold your breath for that one).
Best of luck.
