How does Aircurve 10 S mode work?

Hello All,

New user of Aircurve 10 S. My current settings are IPAP 16 EPAP 12. Don't understand the function of the "Spontaneous" mode? Seems functionally similar to APAP with C Flex set to 3? Except no auto? Really don't get the trigger settings?

I have been using the new bilevel for 2 months now with mixed success with it. Recently some really rough nights with many high AHI 10+ but also many nights very good less than AHI 2. Typically 5 to 6 hours of sleep. I mostly feel fine there are some mornings a little foggy but goes away after I am up a while.

I go to see a sleep doc follow up in a week. I assume he will increase my pressures? As majority of events are OA and H. First couple weeks were tough I was getting mostly CAs and UAs but concluded that leak rate was very high? I seem to have got that under control. Once i got leak issues solved CAs were replaced with OAs and Hs. Does that make sense?

Sure would appreciate thoughts

Thanks

Spontaneous just means that the machine follows your breathing. Switching to the higher pressure as you start to inhale.
Trigger is how sensitive the machine is to the start of inhale, you "trigger" the switch. Higher trigger, more sensitive to your inhalation.

The "S" model is a single pressure model. You have a single IPAP pressure, and a single EPAP pressure. Your pressure is starting pretty high, and some people have CAs when first starting at a high pressure. You are using a pressure supportn(difference between EPAP and IPAP) of 4. You may do better with the Vauto model which allows a range of pressures to be used. With the Vauto you set a range of EPAP pressure, and a PS value. With EPAP set to 15 - 20 and a PS of 4, your IPAP would be 11 - 16. For most people, the trigger settings can be left at the factory settings. My wife and I both use the Air Curve Vauto machine, and the trigger settings have been left at the factory settings with out having any problems, even though we breath at different rates.

Thanks for the replies. It makes better sense to me now. If I am getting this trigger settings are normally left alone. CAs in the beginning is to be expected.

My old auto cpap was set pretty much set at open at 10/18 with c-flex 3. It seems to me didn't spend a lot of time at 18? Usually between 12 and 16 as I recall. Which led me to believe the sleep doctor was on track with the prescription? Would the next logical progression be 17/13 as the OA/H prevention and keep the 4 split?

I am not sure how it will work with trying to get an auto bi-level machine? Dealing with Tricare/military as a retiree can be challenging. My guess would be Dr. would have to determine I have failed this bi-level machine first?

Thanks

All the doctor needs to do is state you need to have a range of pressure instead of a single pressure. I believe Tricare uses the same criteria as Medicare does. As an older retiree, I use Medicare and Tricare for life, and had no problem getting an auto bipap machine. My original prescription said I did not tolerate CPAP, and I was prescribed a range of pressure since they could not get a good single pressure that would work for me during my titration study. My wife had the same problem with her titration, and she has the same model machine as I do.

get some sleepyhead charts up

the s9 is similar to the 10
the VPAP tech starts on page 21
this will help with the S titration on page 35, I would also consider the ST titration for o2 and Vt/TV on page 37 (but of course no back up)
