Question about flow rate shape/flow limitation

Question about flow rate shape/flow limitation
Hi Everyone!

New user here. I was diagnosed with UARS last year (AHI < 5, RDI = 19), and am currently using an APAP. Looking at my data in Oscar, I often notice periods where the shape of my flow rate looks a little jagged or strange when I zoom in. However, these periods don't correspond with any "flow limitation" noted in oscar. I guess I'm wondering if the shape of my flow rate is something to be concerned about, or if I am reading too much into it. I'm attaching a few pictures from last night: once where I saw the more "jagged" flow rates, compared to a period where I saw a more rounded shape, and then also a screenshot of the night overall.

Thanks in advance for any insight!

RE: Question about flow rate shape/flow limitation
Thanks, Sleeprider!

This is very helpful and explains my concern. For what its worth, most of my symptoms have diminished since starting treatment.
This board has been a godsend for someone like me with a recent diagnosis who is unsure of what I should be seeing in Oscar.
