I'm paraphrasing but they definitely told me that I wouldn't be able to use an SD card with the machine. It was pretty evident they weren't aware of how an SD card could be used with a machine though.
Of course they are aware (one would certainly HOPE they read the provider manual), but what we take from this lesson, Boys and Girls, is that DME's in Australia lie just as much as US DME's.
Are there some problems I should anticipate with this?
In the US, most insurers will not pay for the machine unless the user meets usage requirements. So the DME's have to use compliance data to prove to the insurer that you are using the machine in order to get paid by the insurer. That's all the DME and insurer care about. A very few sleep doctors/clinics actually use the data to help a use optimize the treatment. Very few.
In Australia, do you have to prove compliance? Will your health care providers monitor your treatment and help you optimize it? If not, why would you need to let them access your data remotely? You can put the machine in airplane mode to prevent access as long as that won't cause you any issues with your providers.
