I have been a smoker for 25 years and have been really sob lately , I got a X-ray that showed hyperflationed lungs and had to fight with my doctor to get a referral and a test for my lung function so finally got it . He said everything was ok even though I show air trapping . He doesn’t want to see me again until another year and gave no inh

Good patient cooperation and effort, although patient could not meet ATS on
FVC.
Interpretation: Impression: Spirometry is without evidence of airway obstruction. Measurement of lung volumes does not demonstrate the presence of a restrictive lung pattern. Air trapping is not noted. The diffusion capacity is within normal limits. Flow volume loop does not demontrate evidence of a large airway obstruction.
