Help Interpreting my Pulmonary Function Test

What do my pft results mean? Do I have mild, moderate or severe COPD? Is it emphysema? I am a 58 yr old male, 6ft 180lbs, exercise regularly, smoked 2o yrs 1-1.5 pks/day, stopped smoking 25 years ago. Used to SCUBA dive. Stopped SCUBA when symptoms started last July. Asthma as a teenager - none since.

Symptoms: Since 7/15/2001. hoarseness, mild dry cough, lung irritation (like a chest cold). Since 10/15/01. same plus occasional dyspnea (at first once a week now every 3 days)
Dyspnea starts when hoarseness, lung irritation worse. Sleep a lot, usually very tired. Feel pretty good in morning. Feels like a cold that starts every 3 or 4 days. no fever.

Diagnosis that came back with pft said: normal FEV1, FVC, and FEV1/FVC. No bronchodilator reversibility. Increased TLC, RV, and RV/TLC. Normal vital capacity, normal DLCO, normal flow volume loop. Pulmonary function study demonstrates a non-secific ventilatory dysfunction. Elevated lung volumes suggest air trappings consistent with COPD.

The actual pre and post dilator %pred numbers for some of the spirometry measurements were: fev1(94,100), fvc(108,110), fev1/fvc(87,90), fef25-75(59,68), fef50(60,73), fef25(91,102), fef75(44,51), mvv(107,84).

Some %pred for lung volumes were: tlc(136), rv(197), rv/tlc(145), svc(105), erv(127), frc(170), ic(95).

Some diffuion %predicted were dlco sb(107), dclo corrected(107),dl/va(90).

I also had xray and CT scan of the chest. The report said normal for everything except "mild changes COPD". "There are a few areas noted of destroyed lung consistent with COPD.

Thanks,
Tom

As stated in the report of the CT of the chest, you may have mild COPD.  The abnormalities of the Pulmonary Function Tests (PFT
