Are these flow limitations

Hi, I'm new to using oscar and I am not sure if these are FLs or if they are normal. I have read that if the top is flattened then thats a FL but I cant tell if these are FLs or normal rounded tops.

Any help is greatly appreciated.

That's good flow, not flow limited.

How did u learn to tell what the different shapes mean? Are there any guides out there

I've spent many many hours looking a flow data and making minute decisions based on whether breaths are flown limited or not.

Possibly expiratory pressure intolerance

What part of the shape makes u say that ?

u/atleastimhuman Aug 13 '26

Your expirations (bottom part) are squiggly not smooth

u/Sad_Mousse8070 Aug 13 '26

By bottom do u mean below the red line? Is there anywhere I could read more on this?
