ABSTRACT
Introduction -It is observed that our young generation is increasingly being exposed to noisy environment, as they remain engage in such recreational activities like listening music on mobile phones, personal music players or through laptops,ipads,ipods. They are also attending discotheques, rock concerts andvideogames for recreation.Unfortunately not much attention is being given to effect of the increasing trend of prolonged exposure to noisy recreational environmentin the younger generation of Indians.
ABSTRACT
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.
