Impaired Lung Function in a 41-Year-Old Man

What does the following data reveal about a 41-year-old man with a history of occasional smoking? The data suggests impaired lung function in the 41-year-old man, potentially indicating early stages of a pulmonary disorder like COPD or asthma.

The data obtained from a 41-year-old man who admits to "occasional smoking" but reveals no past history of pulmonary problems shows the following results from pulmonary function tests:

  • FEV1% - 82%
  • FVC % pred - 82%
  • TLC % pred - 97%
  • FEF 200-1200 % pred - 79%
  • FEF 25-75% % pred - 58%

These values indicate impaired lung function in the individual. Both FEV1% and FVC % pred are below the predicted values, suggesting a restriction in the amount of air that can be exhaled. The FEF 200-1200 % pred and FEF 25-75% % pred values are also lower than expected, indicating a decreased ability of the airways to transport air.

Considering the man's history of occasional smoking, these findings may point towards the early stages of a pulmonary disorder such as COPD or asthma. Further evaluation and potential medical treatment may be necessary for the individual to address these issues and prevent further deterioration of lung function.
