How to know the PR autosv is working right?

[danielqk]

I am going to purchase a used 2000 hrs PR BiPAP Auto SV Advanced-System One 950 from Craigslist.
The seller said he bought it from a friend DME who doesn't want to fix/support this model.

I can calibrate setting pressure with a manometer but this machine algorithm is complicated
and not simple as cpap or autopap

With all this confusion, why do you want this ?????

What are the problems with the machine? I don't know any individual who can service these, but you might want to PM Accurate who is a member of this forum and services machines.

the modern computer controlled machines usually either work or don't.... they usually don't get 'off'... at least I haven't heard about that happening.

you could always just ship it to accurate for testing if needed.
