Older models use the datacard or a CF card to store data; current ones (like my dad has) have cellular data because they are no longer sold, exactly, but rather provided "as a service" and billed accordingly. They can monitor your usage history (including apnea events, non-sleep and REM sleep), change all the config, probably even brick the thing remotely if you don't pay.[/b][/i][/color] ![Face Palm :palm:](https://www.eevblog.com/forum/Smileys/default/facepalm.gif)

Not sure what you are saying here. Are you saying you can't buy a CPAP or you can't buy one with storage cards? I bought mine from 1-800-CPAP last year, a Phillips Respironics Dreamstation Auto. Mine has bluetooth connectivity with an SD card for storage that works with the Dream mapper app but I don't use it. It doesn't use cellular service.
I dunno then. Maybe it depends on how you pay for your medical care. If insurance pays for the unit, it’s usually provided “as a service”, at least until paid off at ridiculous markup like my first two. The providers get a lot more money in the long run, while the insurance companies get more money in the bottom line at the end of the quarter.
If you’re HMO or “Healthcare Union”, I’d guess they buy outright. Also, they’re not nearly as expensive now as they used to be, and yours might be a slightly older model but factory refurb or NOS.

I’ve seen 3 or 4 new-new machines in the last year; they were all cellular data equipped. I guess I assumed that’s how they all were provided; but like everything in the last decade or so, the crazy economy is making a lot of changes in the way anything business is done.
