From APAP to BIPAP

[Vixoe]

Hey All,
I have bought a second hand Resmed Lumis 150 STA to see if this would make my nights more comfortable. - I am strugling with air getting into my stomach with the APAP.

My APAP machine was set up with pressure Min 7 Max 12 

I have set up the Lumis in ST mode because i am not sure i know enough about the IVAPS mode yet.

I set EPAP to 5 and IPAP to 4
TI Min 0.8 and TI max 1.80

Last night was my first try, and i feel terrible. I'm dizzy and tired.  - Can any of you see anything from the screenshots about what is happening ?
On the plus side i have no air in my stomach today

You very likely overbought on the machine. You probably just needed a VAuto like bilevel, however you bought the one that treats lung disease restricted breathing style. That's what iVAPS is for.

ST is a spontaneous timed mode, it'll time some of your breathing. This too is probably overkill. The ST will only have a single static EPAP and IPAP, where a VAuto like ResMed would offer variable pressures.

Are you just trying to treat Apnea or some lung condition as well? If just Apnea, this will likely be harder on you to tune than what you're in need of.

I am sure you are right, I should have read some more in here before I bought the thing. At least is was cheap and has no more than 600h runtime.

I have no underlying issues other than mild to moderate apnea.
So you dont think I could use it in ivaps mode and make it work?

We will be better able to help you if you set up your Oscar charts differently.  We need to see the whole night's sleep and only show an enlarged section of a few minutes if someone asks you to.

On the first page, we need to see only the following in the order listed below.

Event Flags
Flow Rate
Pressure
Leak Rate
Flow Limits

We need to be able to read to the very bottom of the Flow Limits.

Best of luck with improving your therapy!

Thanks, I will do that, except for flow limits. The Lumis cant show them.
