Health Net and ASV
#11
Although I've yet to even see a sleep doc (Tuesday), I've tried to get a bit familiar with OSA and CSA, both CSR and non-CSR, as well as Complex. So I'll hopefully understand whatever my study diagnoses. I've also acquired and studied the ResMed Clinical Guides for the CPAP and CPAP AutoSet (both E0601, CPAP), S and AUTOV (both E0470, Bilevel), and ST and ASV (both E0471, Bilevel with backup breathing rate). As a tech guy, I understand their different modes of operation. The AirCurve ASV is the only one that allows PS to vary throughout the night and with ASV Auto engaged, the machine has control over EPAP, as well as PS and hence IPAP.

Right.

Also check out the Philips Respironics System One BiPAP AutoSV Advanced with Heated Tube. It has far more settings and is more configurable (and misconfigurable) than the ResMed ASV models.

The PRS1 BiPAP Auto also adjusts PS, but very slowly, such as perhaps 1 cmH2O per few minutes, in order to minimize Flow Limitation and RERAs. The corresponding ResMed AirCurve 10 Auto uses fixed (manually adjusted) PS. Because the standard bi-level Auto machines do not adjust PS quickly, they cannot treat sudden central apneas.

An ASV machine will adjust PS very quickly, perhaps from its min to its max in just a few seconds, to do for us all the work of breathing if we suddenly stop our breathing effort.

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.

That's one thing I've noticed about the AirCurve ASV--very little tweakablility even compared to the bilevel VAUTO. Fine if you want everything automatic.

This is good to know. Thanks for taking the time to reply!
