ANSWER: Hi Justin,

Thanks for giving me a shot at answering your Pulmonary Function Test (PFT) results. My response, in summary, is that I don't really see any glaring problems with your results, but any Reference result that is below 100% is generally considered "sub-optimal" or abnormal. PFTs are a whole separate specialty altogether, and generally a PFT Specialist and Pulmonologist can give you a much more fair idea of what these results really mean. I would like to recommend to you that you consult further with a Pulmonologist.

Best of health to you,

Larry, RRT

QUESTION: So do you think that im in the beggining stages of COPD? that is what i have got from the other 2 respit theripist, i was never a heavy smoker maybe half pack a day and always active.and if so is there a way to fix this from happening im 31 years old.


Hey there, good to hear back from ya. I can't really say you have COPD, because as an RRT I am not qualified to make an official diagnosis of any kind. But there are ways to identify diagnoses based on PFT results and whatnot, and the results can sometimes line up with what we would see in a COPD patient. Not trying to dance around the questions so much, but COPD patients can range in age from 25 to 125, as smoking-related conditions know no age restrictions. Hopefully that makes sense.

Best of health to you!
