Bilevel auto is much like any auto adjusting machine. But, the pressure split between IPAP and EPAP pressures can be greater than on an Autoset; plus the split is constant. The VPAP S9 and S10 VAuto can exceed 20 cm-H2
O pressure. (Upper limit is 25)
ASV tracks your breathing pattern and can adjust on a breath by breath basis; performing an inflation of the lung (much like mouth-to-mouth) to ventilate a person when a missed breath is detected.

WELCOME! to the forum.!
I wish you much success at your next sleep study and also as you continue your CPAP therapy.
I use a ResMed AirCurve 10 VAuto with pressure ranges similar to what you describe. During an in-home BiPAP trial, I was using an Respironics DS760. I liked both of them, could easily adapt to either one. I chose the ResMed, honestly, because I like the form-factor better - it's a bit more compact. I'm actually planning on picking up a Respironics machine as a backup so I'll have both available.
I did find that after a month or so of acclimatization, I was able to tweak a couple settings that made the machine even more comfortable - after the first few breaths, I barely even notice that the machine is there anymore.

Any thoughts about what I need to ask or what I should know or be aware of would be very appreciated. From my research so far which is not a lot it seems that the Resmed Aircurve 10 ASV seems to be a potential machine. At the sleep lab I dont know the model but it was a Respironics machine. I have heard that some people struggle with one brand and that the other is easier to comply with.
A standard bilevel Auto is the best
machine for simple Obstructive Sleep Apnea when uncomplicated by an excessive amount of Central Apnea. However, for those who have a tendency to get Central Apneas, standard bilevel therapy or standard Auto bilevel therapy usually tends to make central apneas worse.
ASV bilevel machines are more expensive, and ASV bilevel therapy is usually more difficult to get used to (inhale pressures range higher, and the machine sometimes seems to have a mind of its own), but it is well worth the effort if an excessive amount of Central Apneas are an issue.
When I was using a bilevel Auto machine I would occasionally still wake up slightly headachy and unfocused, having had more than 5 CA per hour. My ASV machine has solved that problem and is definitely my friend.
For ASV, I think usually (but not always, because it depends on insurance requirements) a separate ASV Titration is required to show that ASV therapy is able to successfully treat your central apnea component.
Take care and good luck,
Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.
