I've been using a ResMed AirCurve ASV VPAP unit now for nearly a year with excellent results. I had a ResMed S9 ASV VPAP unit before that which bit the dust near the end of the two year warranty. My number of events went through the roof for no apparent reason and it took an act of Congress (it seemed) to get anyone to listen to me insisting my S9 was bad. I finally convinced my sleep Specialist I was right and she made the supplier listen to me.
Finally, after much arm twisting my supplier gave me a new Air Curve unit as a loaner, until my S9 was fixed. That was nearly a year ago so I guess it wasn't worth fixing after all.
I love the AirCurve ASV. My AHI and number of events are way down now. Out of the last 340 nights, 83 were 0.0 AHI and 101 more were 0.1 AHI. Not too bad!
I have a question about the data about the data from the AirCurve: Why do all the Hypopneas show a 10 second duration no matter how many there are? I thought it was just a SleepyHead fluke but it's also the same with the latest version of the ResMed software, which I hate. I had several Hypopneas of over 120 seconds with the S9 device and many between 1 and 2 minutes.
I hope to see an update in SleepyHead soon that will help AirCurve users. As it is it's still hands down better than the ResMed junk... Anyone have an idea about the Hypopneas???
