COMPARATIVE STUDY OF PULMONARY FUNCTION TEST BETWEEN SMOKERS AND NON-SMOKERS IN KOSI REGION OF BIHAR

Smoking is well-known to cause respiratory disorders and pulmonary functions decline. Respiratory system evaluation and screening can easily be done by Pulmonary Function Tests. This study was carried out in the Kosi region, Katihar, Bihar, in 74 participants. Prior consent was obtained from the Ethical committee for this study. For this study, computerized spirometer, "RMS Helios 701" was used. In view of increasing behaviour of smoking among the people of Kosi region of Bihar, this study was undertaken for a better understanding of the correlation between smoking and its effects on pulmonary functions. It was observed that pulmonary function in mean +/- standard deviation, FVC was 2.93+/-0.66 litres, FEV1 2.74+/-0.57 litres, FEV1 % was 94.19+/-7.37 and PEFR was 7.69+/-1.74 litres and FEF 25-75% was 4.08+/-1.15 litres. The pulmonary function tests in smoker population in mean +/- standard deviation, FVC was 2.54+/-0.86 litres, FEV1 1.81+/-0.88 litres, FEV1 % was 74.83+/-31.43 and PEFR was 5.98+/-2.35 litres and FEF 25-75% was 2.95+/-1.31 litres. The comparison of PFT in non-smokers and smoker population was significant with "p" value <0.05, showing decreased pulmonary functions in smokers.
