Is the machine Jas_williams purchased for $150 an AVS machine? The reason I ask is -- I continue to have CA events and it is my understanding that an avs machine can treat them.
Yes...it would qualify for the term ASV or NIV (non invasive ventilator) and can do what is needed to deal with central apnea.
In the ResMed model line the AirCurve 10 ASV model is the latest model but the S9 Adapt is just the big older brother of the AirCurve 10 ASV.
Only with the Adapt you don't see the term "ASV" on the outside of the machine...you see "Adapt".
The ASV term is seen inside in the clinical menu setup area though.
There are 2 S9 Adapt models....the 36007 and the 36037.
The 36007 is the older of the 2 models and only has one ASV mode choice in the menu with fixed EPAP...the 36037 had 2 different ASV modes in the menu. One has a fixed EPAP and one has an auto adjustable EPAP as part of the ASV mode.
The AirCurve 10 ASV...essentially a 36037 in terms of available modes and function just in a new package.
I think that they all have cpap mode available but it's not the same cpap mode as a person might have on one of the other models (Elite, AutoSet or even the regular AirCurve) because it doesn't offer EPR and it doesn't distinguish between central and/or obstructive apneas.
None of the ResMed NIV machines (and there are other models in this category that can deal with centrals besides the ASV) will distinguish between central apnea or obstructive apnea...both go into an unclassified apnea basket.
The assumption being that if the parameters are set properly the centrals will be treated and that only leaves obstructives to be flagged.
Now the ResMed ASV models that have the auto adjusting EPAP available...those machines can be dumbed down (tweaking the available settings) so that they function more like a regular auto adjusting bilevel or even an autoset.
So there is a lot of flexibility with the machine if someone knows and understands the various setting options. Heck, we can even make it work like cpap mode if we wanted to.

Pretty expensive cpap mode though so obviously not something that we often want to do.
I have owned and used both the 36007 and the 36037 and both ASV modes have been tried and I DON'T have any problems with centrals...it can be used to treat plain OSA but it's an expensive option when compared to the cost of the regular apap machines and one needs to know what they are doing in terms of the settings and what to expect and look for.
I happened to find some killer hot deals on the machines I used or I wouldn't have done it. They were all used when I bought them.
No way could I afford new. Deals are out there but one has to be patient and at the same time prepared to close the deal fast if a hot deal is spotted because it won't last long. I have been burned twice on a Craigslist deal...once on a M series apap years ago and I lost my money on that one.
Got smarter and the second burn was paid through PayPal and I got my money back. The asshole never shipped but he kept offering it for sale on craigslist even while I was disputing things and in the process of getting my money back from PayPal.
For this reason I will often be more willing to pay slightly more to someone I might know on this forum than what I might spot on craigslist. Even if they got it off craigslist themselves...they are taking the risk that I just don't want to take.
Now if I could find something local on craigslist...yeah...I would go do the deal in person but where I live..it's mostly dinosaur bricks getting offered at 10 to 20 times the real market value. It's rare a good machine at a good price pops up on my local craigslist.
I may have to RISE but I refuse to SHINE.
