Abstract
Background: Major risk factor causing worsening of function of lung is smoking. Several researchers had established changes of pulmonary function on outcome of spirometry test. Our intention was to learn influence of smoking on spirometry parameters of individual living in tribal region of our state. Methodology: Pulmonary function test was performed by group of 50 smoker and 50 nonsmoker subjects of age 20 to 60 years living in nearby tribal locality. Results: Pulmonary function parameters and result of test was compared between group of smoker & nonsmoker subjects. Conclusions: We conclude that mean FVC, FEV1 and PEFR were higher in nonsmoker. Smoking habit leads to definite pulmonary function impairments. Mixed pattern of lung function impairment turns out to be most common and obstruction pattern as 2nd most common among smokers. Keywords: Smoker; Nonsmoker; PFT.
