Can anyone help me understand what is happening?

I am not sure what's happening in the area I circled in red, but it happens to me frequently. There are not always RERA events.

We would need to see some zoomed views
30 min overview
10 min view, a couple
some 3 minute views of the 'interesting' parts

I can’t see it but mine does something like that when I have mouth leaks ( no leak chart)

Thanks for the feedback. 

There are 5 screenshots here:

#1 is the 30 minute period in question. My breathing, I believe, goes from normal to abnormal in this period. I think this because the flow rate narrows around 00:04 mark and I have 2 RERAs during that time. 

#2 is a 10 minute period where my pressure quickly spikes from 15 to the max pressure of 17, which is physician set. This happens earlier in the night at 23:51. 

#3 is a closer (10 minute) view of #1 at the point where my breathing changes from normal to (I think) abnormal.

In the next post, due to the 3 post limit are the following screenshots:


           


Thank you for you guidance and help.

As promised, here are the final two screenshots:

#4 is a 1 minute close up of normal flow rate pattern (normal for me). 

#5 is a 1 minute close up of the abnormal flow rate pattern I am wondering about.

How are you feeling? Your abnormal is my normal haha

Might be different sleep phase?

[SarcasticDave94]

Any flow limits going on in that period of interest where flow rate diminishes?

[Ratchick]

Maybe show us what your flow limits and leaks are like in that times? Perhaps just high level overview at first where we can see a little of "normal" versus "altered".

[smfkdol9392]

Yes, here you go. See attached image:

OK. Here you are - one of these is a zoom in on altered, the other is a whole night. 

My leaks are almost nonexistent, but I have flow limit problems in certain times.

[SarcasticDave94]

My opinion is that flow limits are or could be contributing to the reduced flow rate.

On a hunch, nothing more.
I'd like you to try a cervical collar. You do not have the normal indications we see but the low volume flow is severely flow limited and I suspect you are tilting your chin in toward your chest. Read about via the link in my signature.
