Hello,
I had my first appointment with a pulmonologist, and he mentioned that the upcoming PFT I have scheduled will show if I have aspects of a restrictive defect concurrent with the obstructive breathing (he saw this in the spirometry that the allergist did, and that my PCP did 3.5 years ago). Also a restrictive defect can make an obstructive one look worse on PFT.
Does anyone else have a mixed defect, or know anything about it?
