My sleep therapist just gave me an Amari View (Respironics) and I used it for the first time last night. I really like it as an alternative to the full-face Resmed Mirage Quattro I had. Covers mouth and nose with a pillow-like feel for the nose, so no nose bridge. Felt good, but only first night so far.
I too have an ASV from Resmed, have been using it with very good results. A few months ago my prescribing doctor showed me a letter from Resmed (I think) advising certain patients to discontinue using it. A recent study showed a significant increase in the frequency of heart arrests for patients with CHF with an ejection fraction of less than 45% (I think). That fit me, and I discontinued its use with acute apnea effects evident immediately.
I conferred with my cardiologist and my prescribing doctor and concluded that the benefits of the ASV greatly outweighed the risks for me. I have now been back on the ASV Resmed, with the usual good effects.
So it was quite an unwelcome surprise to hear about the risks, but I'm comfortable with my choice.
I have the Resmed S9 that I think is called an "ASV". It elevates the air pressure when it doesn't see inhaling within a certain time -- I guess that IS how my central apnea is supposed to be handled.
It's been about a year since I got it. AHI 0.0 pretty much every night, an occasional 0.1 after 8 hours with a hypopnea being the 1 event in 10 hours for the AHI of 0.1.
It has worked absolutely fine so far, and your post worries me a bit. I have a home health agency that provided the Resmed, and would replace it if there was any problem. I'm well covered by Medicare, I think, for any hardware problem with the machine.
I hope your experience gets better.
