Question about flow rate shape/flow limitation

[Sleeper512]

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!

Welcome to Apnea Board forums. Read this wiki on cardiogenic oscillations, and let's see if that answers your question http://www.apneaboard.com/wiki/index.php...cillations

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.

It's good to take and interest and take control of therapy. You'll be living with it for a long time. Glad you decided to post your question.
