Background: To assess the pulmonary function among firefighters using Spirometry.
Methodology:  A cross sectional study was conducted among firefighters in Puducherry, India.  Spirometry was done to assess their lung function. The Spirometric values obtained viz., FEV1, FVC, FEV1/FVC ratio, FEF25-75% were compared with predetermined predicted values (expected values) for their respective age, sex, height, weight and South Asian race.
Results: In our study, a total of 115 firefighters working in 9 fire stations in Puducherry were subjected to Spirometry in their workplace itself. Eighty seven (75.7%) subjects had a normal Spirometry (FEV1/FVC ratio>80 %). Twenty eight (24.3%) subjects had FEV1/FVC ratio<80% and were diagnosed to have obstructive airway disease. Out of the 28 subjects, sixteen (51.7%) subjects had FEV1 >80% of predicted (Borderline obstruction). Ten (35.7%) subjects had FEV1 between 60-80% of predicted (Mild obstruction) and 2 (7.1%) subjects had FEV1 between 40-60% of predicted (Moderate obstruction). None of the patients had FEV1 <40% of predicted (Severe obstruction).
Conclusions:  Out of 24.3% subjects who showed evidence of obstruction, 51.7% subjects showed borderline obstruction, 35.7% subjects showed mild obstruction and 7.1% subjects showed moderate obstruction. Follow-up Spirometry in the study group over a period of time could help us in establishing the association between smoke exposure and decline in pulmonary function.
