Hi Jarlo, I just registered on this site, so this is my second post
I used to work as a sleep tech prior to having my own changes in health, and now I use a bilevel AVAPS due to central sleep apnoea.
Having a glance at your nightly reports shown in your last post, I would think it’s very much worth trying the ASV machine, as these are designed to treat the type of periodic breathing that can be seen in your reports (by periodic breathing I mean those irregular flow periods that are represented within). When transitioning to volume support, it can feel a little weird (as opposed to pressure support), however after getting used to it, there’s the possibility of getting a really good nights sleep - and by that I mean you feel refreshed in the morning. Keeping in mind that AHI doesn’t illuminate all the underlying issues that could be causing you to feel still exhausted in the morning (for instance, in my case, I have a very low AHI because my airway doesn’t narrow or obstruct; I simply do not breathe when I fall asleep, and critically, this is not detected by standard CPAP/APAP devices. So as that shows, a low ahi means very little when I am turning blue after being asleep for two minutes when my body is not breathing despite having an open airway). ASV provides very quick flow support and then readjusts back to acting like an APAP device for those moments where flow changes occur. I presume this is why your specialist says to give it a go. Sounds like a really sensible experiment to me
. All the best, and if you’re happy to, I’d really like to know how you are going
