Am a 46 yr old male. Had a PFT done today. 1st ?---why did I pass out while performing the FVC with every attempt. It was not a very pleasant experience. Here are my results. Please explain what they mean. Before I go....I have never smoked, or did drugs.....In 98 I was told I had sarcoids of the lymph nodes. I do get shortness of breath quite easily. had heart test done, appears to be Borderline Normal, lol. Can anyone help me. Thanks in advance.
