Help recognizing events in Oscar?

Hello,

I was wondering if anyone could help me identify these screenshotted events in Oscar and tell me if they are breathing-related arousals (or not). Attached is screenshot of the full night then some of the individual events: https://imgur.com/a/hJsbBqd. Here is a link to the Sleep HQ data: https://sleephq.com/public/ec588ae1-24b ... 31cc0540f9

I have been using my BIPAP for almost 2 years now but have not fully resolved my symptoms. My settings are currently 14 EPAP, 19 IPAP with a PS minimum of 4. My doctor originally titrated me to a pressure of EPAP 15, PS 2-4 and I have tried pressures as low as 10 EPAP, but still didn't feel better so I have slowly increased increased both my EPAP and IPAP without going beyond a PS of 5. I recently saw a new sleep doctor but she only looked at my AHI and didn't really address my concerns about RERAs.

Last night, my AHI was shockingly 0 (it is never this low) but I consistently see these types of events throughout the night and am not sure if they're breathing events or not. They generally look like a spike followed by a long pause in breathing. Even today with 0 AHI and a decent amount of sleep, my brain does not feel fully rested. Am I still having events that the machine is just not flagging? Are all the "spikes" in the data arousals or are those normal?

Any input would be appreciated, thank you!!

What are your symptoms?
When did you decide on a lower EPAP than the doctor recommended, and why?
Did you have a lab titration?

wih a PS 2-4 and I have tried pressures as low as 10 EPAP, but still didn't feel better.

ResMed machines like yours don't have variable PS.

Looking at Oscar, you're still snoring - albeit gently, and you have a pretty constant leak.
If those were my leaks, they would wake me up - so for me, I'd have to handle both the snoring [assuming it's not an artifact] and the leaks.

Take the cursor, point it to all those place where you see you breath flow point up sharply, and check what happens in the leak line. I wonder if you not going through repeated cycles of mouth leak, arousal, close mouth, fall asleep, mouth leak, etc.
I also wonder if that snoring in related to the open mouth and leaks.

Have you ever tried an FFM or taping?
Did you ever try EPAP= 15, as recommended?

Read this thread and pay attention to the examples and explanations I wrote.
See if that helps clear things up....if not, ask what needs to be cleared up better.
