I got a call yesterday from the DME and she said they will be ordering the 10, but are waiting to see if insurance will pay for it or rent it.
If I had a prescription for End Expiratory Pressure (EEP or EEPAP or EPAP) in standard ASV therapy mode, I would use that, or I would ask if I could use ASVauto with Min EPAP being zero to 2 lower than my prescription for fixed EPAP setting and Max EPAP set to zero to two higher than my prescription for fixed EPAP.
On my machine which only has CPAP and standard ASV therapy modes, I raise EPAP when I see rattiness (stop and go) on the "Flow" waveform during exhalation, or obstructive apneas (which have no Flow during the apnea). Negative values of Flow are intended to represent the rate (in liters per minute) at which we are exhaling air from our lungs during exhalation.
On the new AirCurve 10 ASV machine, to keep the EPAP from raising too high, I would try using standard ASV mode (not AutoASV) at least temporarily if painful or troublesome air swallowing (aerophagia) or other problems arise from high pressure when using ASVauto therapy mode.
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.
Thanks Vaughn. I looked at my RX and the range is 5 to 15. I am waiting to hear back from DME to get machine, but I will look at the settings when I get it. I had the S9 ASV for my sleep study and didn't notice any air swallowing, but did feel great in the morning compared to the cpap
I have both the S9 ASV and the AirSense ASV with about a week on the latter. My perception so far is that the AirSense seems a little less aggressive when ramping up to the backup rate. I find the AirSense more transparent. Other than that, the things I like about the newer unit is that the display shows the AHI at a glance when I turn the machine off, and I like the idea that SW could be upgraded on the unit. I'm still in rental mode for the new unit. If it is too pricey after insurance kicks in on the final purchase, I would be happy with just using my S9 model.
