Anyone have any idea what this machine is actually worth? Cpap.com has a price of $5800 on it. What year vintage is this machine? I see there are no reviews for it.
jonny, your equipment profile lists a ResMed S9 Autoset as your main machine.
Just wanted to check to be sure you are not interpreting the word "Auto" in the name "Respironics BiPAP AutoSV Advanced" as meaning that machine can be set in an autotitrating mode that will work in the same way your Autoset does, or even in the same way a Respironics autopap works.
The "SV" in the name of the machine you're looking at is "servo ventilator." And the word BiPAP in the name means the machine is a bilevel machine -- separate EPAP/IPAP pressures are set...not a range of just minimum/maximum pressures like in your Autoset machine.
However, you can use that SV machine for straight CPAP therapy, or as plain bilevel therapy if you don't want to get into servo ventilation. You might find that either of those ways of using it give you effective therapy. Bilevel therapy is particularly comfortable...if your breathing and a particular brand of bilevel machine gee and haw well together.
What you can't do is use an SV as an "autopap" in exactly the same way an autotitrating CPAP machine (like your Autoset) "autotitrates." Bilevel Auto and Bilevel Auto SV machines don't have an "auto" mode like your Autoset machine has. They are first and foremost "bilevel" machines...a different breed of cat from CPAP and autopap.
All that said, I'd jump at buying that machine if you can get it at what you want to spend for a "standby" machine. You don't have to use it as a "servo ventilator."
Worst case scenario, if the machine doesn't suit you well, you can always sell it at CPAPauction.com. Quite a few people in this forum might be looking particularly for an SV machine. That's a pretty low number of hours, so if you found out pretty soon that you didn't like the way it delivers therapy, there might be several willing buyers for it right here on this forum.
Here's a screenshot of a page in the Provider manual explaining how a Respironics BiPAP AutoSV can be set to operate as a CPAP or as a Bilevel, instead of being used as a servo ventilator. If you get the machine, I'd suggest setting it to act as a bilevel:
