No, I'm certainly not. But disputes arise with insurance companies all the time (I'm going through one with another provider, who claims I owe them money, and the insurance company assures me that I don't owe them anything, but they keep harassing me anyway). Medical billing is such a mess that I can see them using this as leverage to get money out of people.

OK so being proactive then, we should challenge someone to hack a disable on the modem... or on the remote setpoint changing function.

I have an Airsense, and have done a bit of research on this topic.. Here is what I have found out.. The modem works off the Cellular network, and is used not only as a compliance and settings verification by your DME, but also the data is used by Resmed with their "my air" program, which is how you go about finding how well you slept last night based upon a score of 0-100... The score is weighted like so... Usage (0-70) Mask Seal (0-20) Events per hour (0-5) <--- Nowhere can you check your AHI.. and Mask on/off (0-5) While this is a more flashy version of the AHI 7 and 30 day scores of previous generations, it is a really meant for those who are not interested in, or can not understand more raw data like numbers and especially what Sleepyhead gives you..

Not only does it do the whole score thing.. Take my last nights sleep for instance... I had a pretty bad air leak a few times during the night (new mask) so in the morning, checking out the "my air" it featured a couple of videos on the "my air dashboard" regarding getting a good mask fit.. for the quattro fx I used that night.. Granted you have to specify what mask you are using, but it is great that it will provide more customized video and information based on your sleeping habits from night to night... Again, it is more for the uneducated user though.. They also sent me an email telling me that my mask fit may not have been the best as the leaks have been higher than normal, and goes on about how to best manage air leaks.

It is a pretty slick setup all in all..

Now, back to the Modem.. As I stated earlier, it is a Cellular modem, most likely working off something called a GSM network (which is the standard network type in Australia, and used throughout the world) The "hackability" of it would be quite low as most phone hacks involve "spoofing" the SIM card data, and passwords for access to emails, photos and such.. Imagine rerouting a package delivery rather than an actual break-in. Also, as I am sure they would be using standard encryption and the data is not voice or a standardized file type (at least I hope not) It would be difficult to decrypt due to the fact that you would need to know what your looking at and for... More than likely the "modem" is not making "calls" but rather using SMS (Text messages for us Americans) to send data, which would be a more efficient and cost effective way to send data back and forth.

I hope I did not make things less clear..

There is a valid concern having nothing to do with the settings. The data provides a tidy snapshot of someone's sleep patterns, timing etc. Could be valuable to someone is some scenario who can get their hands on it. I have not researched how or if HIPA would figure in to design and encryption standards for transmitting this data, but I can think of a few obscure scenarios where that data would be valuable to another. One more reason I am happy to have fired my DME and their wireless big brother compliance checker.

Actually, hacking GSM is not that difficult, but the hacker would have to be within radio range of the cell modem. You don't hear a lot about hacking into your phone via GSM, because it's not that profitable in general.

The central servers are a better target because you can access it over the internet from anywhere in the world and get access to all the connected CPAP machines at one time. However, there doesn't seem to be a lot of motive to do this to CPAP machines. Someone might very well attack the server to use it for spam, stealing information for identity theft, or other nefarious purposes, but they'd probably have to spend some extra effort to screw up CPAP machines. That's possible, but probably not that likely.

ISIS has a grand plan to hack into and trigger RERAS in thousands of Americans on Aircurve10 wireless cpaps, thus wearing down our resolve and military readiness...

All those sleepy infidels will never be able to fight!

Speaking of this, my DME just sent me supplies which I didn't order and which my insurance won't cover. I plan to file a fraud complaint tomorrow...

I'm a S9 user so I don't have to worry about this problem. If you are worried, why don't you put the AS10 in Airplane Mode and shutdown the modem. If anybody calls you about it, you must have turned it off by mistake.

I love it.

Cigna-Sleep called me to ask why I didn't send the SD card in for verification? I had never gotten anything, but they do that at three months then six months. Uh, OK. "We'll send you a card next week". Week goes by, and I call them, turns out since I missed the first window, they said they will just do one SD card. OK.

Out of blue, Apria sent me a modem to install. Gee, isn't that more expensive than mailing a SD card? I installed it, and have good communication. Now I'll just wait for Ring Ring.....

So, who's paying the cellular charges?
