I was diagnosed with complex apnea over a year and a half ago. My split between OSA and CSA is about 50/50, which is apparently unusual (I'm 39, and technically obese, but losing 15kg didn't fundamentally change my apnea experience, although it did get a bit better.) I don't require much pressure -- it's 6/10 EPAP/IPAP -- but I tried for two days when I was diagnosed to get used to CPAP and I just couldn't, so I had accepted that I needed BiPAP or VPAP or whatever.
Consequently, I have a Resmed VPAP ST which, after much desperation and difficulty, I got used to; I sleep acceptably under its care. However, I pay a very large amount per month to use this (I am renting it from a local company in Ireland) and it's a very large amount to buy outright (upwards of $3k?) so I started wondering whether there was a workable alternative to my current setup. I find my apnea particularly tiresome when flying, which I do a fair bit for work, because you can't always rely on cabin power, and the first battery I got was DOA. I've also left the machine behind multiple times at airport security when stressed and running for flights etc.
Anyway, I read about the Z1 the other day and I'm wondering if this is a potential way to solve my problems. A CPAP, but with lessening exhalation pressure support? So tiny it could fit in my standard backpack? Is it a possible alternative? Sadly it seems I cannot test one and give it back if I can't get used to it, because of the federal regulations around medical devices. But I don't want to drop $600-$1200 on a solution if I can't use it, even if the eBay resale value is high.
If you were in my position, what would you do?
