The lung parenchyma is that portion of the lungs involved in gas exchange. The most prominent structure in this region is the alveolus. if there is scarring in small airways it will trap the air.
I am surprised pulm md didn't order high resolution CT as this one of most accurate for air trapping. please ask for it.
proper 6 min with oximeter on. if your hands cold, it can be taped to the ear.
the whole point of the test is to measure exertional hypoxia. pre and post is not the accurate results of the test.

Exercise-Induced Oxygen Desaturation during the 6-Minute Walk Test

Well, now you know why I’m going to Mayo.
I will say they did a ct with contrast, if that’s any help. As for testing o2 levels during the walk, I had a boss who used to say “there’s nothing common about common sense”🤪
I woke up with a cough and scratchy upper airways and running a low grade fever. This could have something to do with my lower than usual levels today, but not all the time.
I did an at home Covid test; it was negative.
I have an appt tomorrow with my pcp and I will talk to him.
BTW, my DLCO was normal on the test.

looks like the study I referred above. they also checked pre and post o2.
but I have read other studies where it was done during the walk. its common sense to keep oximeter on while walking 6 min.
