I will add that on my DreamStation machine, I have adjusted my own pressures, but if I leave the modem in for more than a few hours, the DME-assigned settings will kick back in and return it to the default setting (which happens to be wide-open or pressure set to the 4-20 cmH
2O level. Unacceptible for me.
So, I've simply removed the modem (it's as simple as unplugging the machine and sliding the modem module out).
But, in order to keep getting regular CPAP supplies, the modem needs to communicate with the DME and/or sleep doctor to ensure I'm compliant with my therapy. So, as the modem needs to transmit compliance data, once a month, I put the modem back in and go into the user settings and select the option to upload data. That process usually takes about 3-5 minutes or less, then I unplug the machine again, and remove the modem until next month.
Doing it this way makes sure they cannot remotely change my settings. If I leave the modem in all the time, my settings are eventually changed to whatever they set it at originally.
This has proved to work fine, and my DME and sleep doc have no clue that I don't regularly keep the modem in. And my sleep doc even knows that I adjust my own settings and is fine with it, after I a brief discussion that revealed to him that I actually DO know what I'm talking about.
That's the nice thing about the DreamStation machines - the modem module is easily removable, unlike the ResMed machines that have them hard-wired into the circuit board.
If you're no longer required to prove compliance or you purchased your machine outright and you don't want any of your data to transmit to the "mother-ship", then you can remove the modem and keep it out all the time. Just make sure your insurance company, DME and doctor aren't going to need that data for continued coverage.
