On ASV but considering change to AVAPS

[GearChange]

Hello,
This is my first post and as recommended I searched this topic before posting but without much luck. So if anyone has posted it before, just send me a link to the conversation otherwise I need some input with this and I am hoping to get some ideas.
I am a CSA patient and have been on ASV for a couple of years now. My machine of choice is DS-1 BIPAP Auto SV, however I kind of panicked and got a Resmed Aircurve 10 ASV when the "recall hit" earlier this year and after using it for a few months, I went back on my DS-1 because I just couldn't sleep too well with the Resmed.Of course I defoamed my DS machine initially (even though I had never used an Ozone cleaner like SoClean) but when replacement kits started to come out, I just got a safe replacement sound abatement foam kit and here I am and that's my brief background.

As for my question, I have recently been diagnosed with mild to moderate COPD and I am not sure if my ASV therapy is going to be effective , given that I need to target a minimum tidal volume which my ASV doesn't necessary do. My understanding of the Dreamstation algorithm is that it does a great job of targeting Breath Rate with its BR backup rate but not Tidal Volume which looking at my OSCAR graphs can be all over the place with a variance of about 300ml or so, overnight. This also has an effect on my oxygen saturation levels that tend to drop during the night by about an average of 4%-5% on ASV, while it doesn't normally fall below 92%- 94% range. (without the machine my sleeping SpO2 can fall below 85%)

As or my query:
I have been researching AVAPS machines as they are specifically designed for patients with pulmonary functions impairment, even though my COPD is at early stages of progression.
My question is: If I were to transition from ASV to AVAPS therapy, will the new therapy be able to take care of my central and hypopnea events.?
FYI my Polysomnography test results of two years ago (when I was finally prescribed a ASV) shows that over 90% of my apnea episodes are Central and my AHI without a machine, averaged a whopping 58 .

With the title you wrote, some members experienced with those types of machines will come along to help you. In the meantime, you might want to read what the AAST has to say --->

Thank you.
Interesting that you mention Keving Asp blogs. In fact I read his stuff regularly and happened to have read his rundown on AVAPS.
as for ASVs , I have been on ASV for so long that I have have gained a deep hands on experience of them, with at least 2 models, the Resmed and DS1 ASV.
In fact it was Kevin's article that sparked my interest in moving on to AVAPS and it is also exactly what I will be talking about with my RT next week, although I am very doubtful that my sleep team has had any experience with non-invasive AVAPS for home use, as this thing is pretty much a fully functional ventilator, more so than it is a CPAP. In fact there's a video on youtube that some professional sets up an AVAPS machine to act as a full invasive ventilator...Great for when hospitals run out of ICU ventilators.

My thinking is that if this thing monitors every breath, like an ASV does, then it can take care of apnea events as a peripheral function alongside its primary function which is to maintain a level Tidal Volume rate and keeping Oxygenation up.
