ASV is also a lot harder for many people to adapt to.
that's actually pretty much what you do with a resmed S9 vpap adapt 36037... there's only four settings on it at any rate.
Yes, the S9 VPAP Adapt pretty much takes care of adjusting itself.
But ASV can be hard to adapt to, in addition to getting used to the machine having a will of its own (which, while very annoying at first, is actually the least difficult thing to get past).
The ASV feature requires Pressure Support (PS) to be high during central apneas. If a patient requires both high EPAP to prevent obstructive events (up to 15 cm H2O, the highest the S9 VPAP Adapt can provide) plus high Pressure Support to treat a central apnea, the EPAP + PS pressures combine, making IPAP approach 25 cm H2O. This makes aerophagia hard to avoid, and to prevent bothersome mask flapping a mask liner may be needed (which may touch the eyelashes and be annoying) and the mask straps may need to be uncomfortably tight.
To keep our overall pressure needs as low as possible, it is important to be sure we avoid a sleep position which makes our obstructive apneas require more pressure to treat.
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.
