RESUMO
Objective : The present study was aimed to evaluate the influence of smoking on pulmonary functions. To study the differences in pulmonary function test values in smokers and non-smokers and their variation from other reported values for smokers by other studies. Materials and Methods : In cross sectional study spirometry data of 51 smokers & 54 non-smokers were collected by RMS Medispiror computerized spirometer. Expiratory flow volume curves were recorded & FVC, FEF „„, PEFR, FEV„ FEV,/FVC ratio were obtained. The data were compared between smokers and non-smokers group. Results : PFT parameters FVC, FEV„ PEFR, FEF„, and MW were significantly reduced in smokers group compare to non-smokers group (p< 0.05). The PFT parameters markedly decrease with increase no. of cigarette smoked per day as well as increase duration of smoking. Conclusion : The present study brings out substantial variation in most of the parameters of PFTs between smokers and non-smokers confirming PFT values are less in smokers due to toxic effects of tobacco smoking on respiratory system & is the major cause of obstructive lung disease in Indian population.
