Damn it, I just sold an ASV. It’s a bilevel machine, or CPAP with different pressures for inhale/exhale, that forces a breath whenever it detects no attempt to breathe, aka a backup rate. You probably know what it is, but that’s the machine you need.
At least in North America, getting insured for an ASV through the proper channels can be a tremendous hurdle.
Many people just buy a machine out of pocket and titrate themselves with the program SleepyHead, now called OSCAR.
You can often do better that way with the help of the apneaboard or cpaptalk communities than what a sleep physician or supplier can do for you. Patients need to learn how to readjust their settings as they see fit anyway. The machines are actually a fraction of the prices that medically insured suppliers sell them at if you know where to look. Secondwindcpap is the best online reseller retail store with warranty or you could head over to cpaptalk to post an ad but you won’t have a 2 year manufacturer’s warranty buying second hand that way. Let me know if you need help looking for one.
Resmed’s latest one from 2014 is the AirCurve 10 ASV, the one before that is the S9 VPAP Adapt w/ ASV. They are functionally the same. These machines are pretty much self titrating and offer the best care for most people.
