Info: the ASV has 3 modes, CPAP which is static single pressure, ASV with static EPAP and a PS range Min and Max, ASV Auto which has both EPAP and PS as ranges Min and Max
No standard bilevel here.
I have noticed on others and their OSCAR charts with ASV, it's somewhat difficult to edit for better Flow Limits control. I'm supposing it's due to the way the ASV algorithm runs.

I need help to adjust my Asv settings, or maybe wrong machine?
I even tried to put ps down on 0 at some of the pictures.
I suffer mostly from Oa, and I actually don't have Ca's , that's what my test said, that is why I thought I would try to change ps down to zero, because I heard it's mostly for ca's. I know I need to have a difference between Ipap and Epap and I can only get that by chagning the Ps min so... But Ps can also help if you don't have Ca's?
I know it might sound strange I use asv, but I thought it was the ultimate machine and I had some ca's back on cpap due to high pressure probably.
I often have Arrousals if that's when you wake up, I don't know if it's due to the machine or other stuff. But I often wake up 2-4 times a night.
Also my pattern often seems strange on the flow rate.
I am curious if some can help me with another settings I can try or something else.
extra pictures of different settings I tried before
I have merged 4 therapy threads with the same basic theme of optimizing settings. We try to keep an individual's therapy in one thread so we can easily review the history and see how any changes have worked out.
You should not focus on the appearance of your flow rate wave-form. Your therapy efficacy is typically less than 1-AHI and over 8-hours. I'm not seeing a problem here that requires setting changes to resolve. You might even be happier keeping a qualitative therapy diary that notes settings and how you feel, rather than looking at the charts.

The pressure on the ASV is supposed to increase to reduce events, so I'm assuming this is what's occurring.
I don't think you'll be able to directly address Flow Limits with ASV, because to do so might be opposite what's needed to treat Central Apnea, which is likely why you're on ASV.
It would be much better to keep therapy questions all in one thread, so I'll ask for this to be merged.
I think you'll do better with other ASV settings. This may address FL and snore as a result. However you'll need to try and see if it does.
Maintain ASV Auto mode
EPAP 6-11
PS 3-12
Makes IPAP 9-23
I've suggested increasing EPAP min slightly, and PS min about double what you have now, and PS Max adding 4. You likely need more separation between EPAP and IPAP.

Sleeprider is correct about Positional Apnea patterns. I missed that aspect. This would account for increases to pressures, even though it won't fix the Positional Apnea.

okay so do you still suggest the changes or should I let it be as it is? since if it's my tongue rolling back, then pressure won't help I guess, but I read a Soft Cervical Collar might help, but it's not a problem that ouccur that often I think, so should I just ignore it.
