AirCurve ASV vs Vauto (is ASV king of the hill?)

[Carnal]

My brother uses a Bipap & thinking of getting a spare for him and a toy for me to play with first.  (No death threats please) I'm new to cpap, but I frequently woke up at the beginning with the feeling of suffocating, & would rip the mask off.  To hard to exhale.  Set EPR to 3, & working my way back up to 1 or no EPR. Only 1 mo on CPAP & must make apt with Dr for follow up & discuss the more involved overnight sleep study I had.

Initially I was searching for a low hours Vauto. Then I read this...

On a 7-year old thread here that user RobertBuckley said: 
Responding to Sleepy 1235's original post with an emphasis to his the money is no object, I might say get yourself an ASV machine, for the following reason: It can be set to act in the same way as any of the lesser or dumber machines (i.e. CPAP, BiPap, fixed, autos), BUT can provide therapy that, while you may not need it now, you may in the future - and you will not have to upgrade the machine - just change the settings. Especially valuable if there are Centrals occurring, which can be treated using an ASV.

I this all true? Can one really get an ASV to act like a Vauto?  Or even an auto-CPAP.  Or maybe possible, but the settings are too numerous?

 I see low hr ASV's online for not terribly much.  It seems the price difference between high end machines and medium line machines become more irrelevant when used.  Mostly for the fact for any one identical machine one person will ask for $50 in the used market and another person will ask $600. For THE SAME MACHINE!  One person just wants to dump it, and another thinks it is gold plated (or is smart, had to pay for it himself & wants to recoup investment).  Anyway I HAVE seen Vautos and ASVs for WAY less than even recalled gold-plated Dreamstations

Tell me what YOU know Thanks, Brian

Too good to be true? Yes more or less.

The explanation is this, from a former ASV user no less, ResMed's AirCurve 10 ASV has a CPAP mode that is single pressure, static. It has 2 ASV modes, ASV which is static EPAP - exhale, and ASV Auto - EPAP range.

It will treat these: Obstructive Apnea, Central Apnea, and Hypopnea. That's the good.

The bad: it's probably harder to adjust to, is NOT good for those without Central Apnea, is more expensive.

If you have Centrals, then it is for you. If not, then it's not so good, and likely VAuto will be better.

Follow-up with your sleep study, and the members can help with this decision.
