New AirCurve S10 Vauto set at fixed pressure

New AirCurve S10 Vauto set at fixed pressure
I just got my new machine this afternoon,  and it's set fixed at 16/12. What would be suggested settings for auto?

If used, a factory reset first, to make sure all settings are in default

Mode: Auto
Min EPAP=10 a bit below your fixed pressure settings
Max IPAP=20 (or 25) it should not make much difference unless issues are uncovered
PS=4

Thanks With a new machine, and a new type of mask, that seems to be a good starting point. If it hovers around 16 then the titration must be close, depending on AHI count. If not, we can monkey around with it

Well, last night really blew. I had a lot of large leaks, my pressures were 18 at 95%, and my centrals were up there as well. I wound up taking it off so I could sleep. I'm going to reduce my maximum to 16, and try to get some baseline to work with. Too many variables to work with at one time. I'll post some charts when I have a better handle on what I need to ask about.

RE: New AirCurve S10 Vauto set at fixed pressure
We really can't judge either pressure or events when large leaks are present. Just a few guidelines. For flow limitation and hypopnea we increase PS, and for centrals we decrease pressure support. The need for higher EPAP min is only indicated when obstructive apnea are present, or in rare cases to increase oxygen saturation. In general, fixed titrated pressures are too high, and with auto pressure a lower starting point is usually better. If you are prescribed bilevel due to central apnea, the titration study is nearly always invalid. It would be interesting to see your titration results where alternative pressures were attempted to find the optimum.

So it seems, Sleeprider, the deal is to bring the leaks under control. The PS was set at 4 by the supplier. I DO have CA issues. I had two nights of studies;the last one involved oxygen as an effort to help with the CA. For some reason, that night is not listed in the report as having occurred. I'll call the techs today to ask about that.

It depends on what level of issue there's found with Centrals, and what category they are, but if CA are the main issue or big enough to block regular PAP treatment, then ASV is the best tool. Its backup rate being the secret sauce that a VAuto doesn't have. However if the CA trouble is on the lighter side, the trigger setting at high or very high may help.

So what does the sleep reports say exactly on the Central Apnea issue? Let's start there.

PS looking back at posts in June on another of your threads, CHF is involved, and you mention your LVEF at 20%. This still is a very prominent aspect in my opinion. I believe the VAuto might become overwhelmed with the CA present in that prior thread.

I withdraw my above advice because of what Dave mentioned. You are in serious condition and my post was made without any regard to that. ALWAYS maintain your history by posting in the same thread.

I also was unaware of the CSR and central apnea issue. I'm am certain you have been improperly prescribed a Vauto rather than ASV. The only way we can know is to see the data from your sleep study and the current machine results.
