It will backup your breathing with pressure support so you won't have CA, but I think you will end up with nearly every breath being timed rather than spontaneous. That is the advantage of the low minimum PS on ASV. With ST you get PS all the time and we know that causes the CA. Document your experience and keep some stats like B.P. heart rate etc. If you tolerate it and it works, that's great. If not then you need to backup why you are "intolerant".
A couple Philips SV units on SecondWindCPAP for $1300 FYI.
You know, after using the CPAP, and looking at the differences in the SpO2 chart from my wrist oximeter, I can see why I was feeling so tired.
I would go through 20 min. periods where my saturation was dropping from 90s into the low 70s. Sometimes two or three a night.
Not so with the CPAP. Just a couple spikes into the high 80s, and I feel the difference with just a few days under my belt.
Point is, it's kind of a window into what's going on through the night.
I'm hoping I can use this SpO2 information and adjust the ST to minimum pressures. That, along with the data from the machine.
Although the ST will mask centrals, it does indicate spontaneous vs timed, so maybe I can use that to judge things.
So I'm going to add this to the record keeping you mentioned and see how it goes.
I'm really looking forward to ANY machine with backup.
I still experience events where I have to catch my breath just as I'm drifting off to sleep.
Jars me awake, and repeats for a while.
And even though the CPAP is only 5 cm, it does take some effort to exhale, so the ST being a respiratory assist device rather than PAP, it should be even more comfortable falling asleep.
I know I'll probably need to tweak the settings a bit to get the IPAP and EPAP timing just right.
I remember during the PSG the IPAP time was too short and I couldn't get a full breath.
Had to lift the mask off and get a nice long breath.
I couldn't fall asleep until I found a way to trick the machine with a short exhale to get another IPAP cycle.
Thanks for the SecondWindCPAP tip.
I had contacted them about purchasing a AirCurve 10 ASV, but they needed a prescription.
I should be getting approval from Medicare soon, and once my co-insurance deductible is met, everything is covered 100% till next year.
It's been over two months, tilting at windmills it seems, since my initial appointment.
Now I'm getting anxious.
