FEV1/FVC among smokers and non smokers: A comparative study
Journal Title: Medpulse International Journal of Physiology - Year 2017, Vol 4, Issue 1
Abstract
Background: Respiratory Physiological changes in obesity are decreased overall compliance, increased airway resistance and shallow breathing pattern. These changes are due to increased intra abdominal pressure, decreased chest wall expansion, reduced small airway caliber and adaptation to the increased load. Methodology: The study was conducted at department of TB and chest diseases, medical college. Tests were carried out in the laboratory and these tests were done in chronic smokers who attend in the smoker's clinic at morning hours. Here pulmonary function test are done using spirometry. Results: In smokers, the smokers with normal weight the mean is 81.89 and the standard deviation is 23.10. In smokers with overweight the mean is 78.29 and the standard deviation is 21.61. When these values are chi-square test, it is found that there is significant difference, according to the chi-square test the P value is less than 0.05 Conclusion: The effect of smoking on FEV1/FVC is more affected in overweight group of subjects than the normal weight group of subjects.
