It's got a version of AVAPS which can be applied in various modes. See Sarcastic Dave's 3/9 response. It has CPAP, bi-level S, ST, T, and PC modes, most or all of which have the settings for what they call EVAPS, but I haven't tried them because I don't want to do it uninformed or for no reason.
It's worth noting that it doesn't have full FDA approval yet. It's still under emergency use authorization. I've been really happy with build quality, algorithms, etc . But it would be really interesting to have someone familiar with ResMed devices compare how they feel.
I'm not the best test case for the advanced modes, though, I don't have severe apnea, although my father did, and his father did, and I was having oxygen drops down to the mid to low 80s sometimes. I've never had a high AHI and I suspect UARS.
I originally bought the resvent 20A , The Apap from
Supplier #40 after monitoring my and my family's oxygen for years using their devices. One of my main criteria was having the 30-day return because I'm very chemically sensitive. I had read that the resVent devices had a very good German foam,. I have not been able to confirm that, But I did read reports of ResMed users experiencing off-gassing especially on the new 11s. The unit I got already had 500 hours on it, because of their return policy presumably, but it had almost no off-gassing and what it had was quick.
Then I got a used Vauto but fragrances made it unusable for me. I cleaned it as well as I possibly could and got a new hose and a new humidifier and even replaced the output valve. I tried it for a couple hours a couple of times and got really bad headaches. But a friend of mine isn't bothered by scent and she needed one badly, so that worked out well. The algorithms felt really good to me and it kept my oxygen up.
My doctor prescribed a Bi-Level based on my Oscar data, and my insurance has too high of a deductible to be worth going through. They wanted to charge me $600 for discontinued Phillips sleep test, so I just went through my primary care doc and bought out of pocket.
I really like being able to fine-tune the feel of my treatment. I've been happy with the device, but that said, I wouldn't recommend it for anyone who's not already quite familiar with the different modes of therapy and what settings to use and what to be cautious about.
