(edit: removed redundant rants and added updates)
I recently got diagnosed with a condition (sleep apnea) which means I need to use a machine (CPAP) to have a proper sleep, probably for the rest of my life. The doctor wanted me use the device for a few months, and bring the "report" generated by the device to monitor my progress and discuss further treatment.
I thought it would be a simple task, like using a program or accessing a local network service like a printer would and download a file. However, as I consulted to the device distributors in my area... their sales pitch (disregarding the actual medical functions) were:
A) The machine is constantly connected via wi-fi or cellular to manufacturer's server, and user downloads the report via manufacturer's website or an app.
B) The machine has an SD card slot to which data is copied, but user have to bring its contents to the authorized distributor so they can convert them into a report file.
TL;DR: Very unsatisfied with either options. I never asked for this.
Update #1: For the reports, there's a program called OSCAR (www.sleepfiles.com/OSCAR/) that supports conversion of SD card data. Check device compatibility first. For sleep apnea related discussion, there is a forum (www.apneaboard.com) dedicated to it.
Update #2: From all the available brands, I'm inclined to buy a Chinese brand (Yuwell) simply because of costs alone, even if it is not supported by OSCAR. I see a lot of people recommending ResMed (which has OSCAR support) both online and offline, but the cost is prohibitively expensive for someone in my financial situation with local market prices. Still have to think about it.
Update #3: There's an asshole in the comments arguing "what's so special" about sleep related statistics being copied around. I concern was how those statistics get associated with customer identification (metadata) as distributors often do. Anyways, won't waste my time with the "got nothing to hide" type of dumbfucks.
I have and use a resimed that does the phone home option. Once my doctor got what he needed I put it in airplane mode.
Distributor used the stats while I was reporting to call me and tell me I need new filters or other parts. I lol’d and bought them online for way cheaper. They stopped trying even before the doctor got all the data he needed.
Also, AFAICT it’s only data out, so I’m not worried about some exploit being delivered to the machine.
Final thought: I work in med tech. We have better security than credit agencies because we get fined more if we screw up. Personal data leaks are so common no one even cares anymore, but leaking someone’s medical info will shut a company down. You are likely safe, but ultimately never as safe as a “dumb” machine would be except they just don’t exist anymore.
Actual final thought: you will be amazed at how much better you feel every morning after actually sleeping instead of the dirty pseudo sleep you’re currently getting.
Thank you. I asked some acquaintances in health industry and received similar answers.
