Flow Rate - what is this ?

Flow Rate - what is this ?
Hi Folks,

I was looking back through my data on Oscar and I noticed something that I haven't seen before on my flow rate graphs. I probably have around 2 years worth of data which generally shows an  AHI of < 0.8, but I wake up just as tired as when I went to bed. My flow rate generally has a lot of noise, swings between +/- 30 and I have around 25 recovery breaths over an 8 hour period....

I noticed, looking back, in March, one night there was a 30 minute period from ~ 2:45 am to 3:15 am where my breath dropped to +/- 20, the pattern was uniform and rhythmic, resp rate was a flat 10, and my exhale was more relaxed with Exp. Time ~ = Insp. Time. I'm assuming this is pattern is good but what is it, how is described ? What are some of the key words for a search for treads here, or on Pubmed, related to this pattern ?

Attached is a screenshot of the overall night from March,
   

a 2 minute view from the 30 minute period in question,
   

and a typical recovery breath (for me) with a more aggressive exhale and a pattern that I typically see night after night...

   

Now that I'm looking for this, I see very small periods  2 -5 minutes of this pattern, here and there, but not very often

Thanks for any feedback...

Rob

Welcome to Apnea Board. You should include one OSCAR shot of the left panel being visible so that the info there is on record so to speak. Please review the link in my signature for chart setup for suggestions.
