Abstract

ABSTRACT: Tobacco smoking is highly prevalent all over the world. Tobacco smoke affects almost all the systems of the body. This study aimed to see the effects of smoking on the respiratory system. For this study we selected 30 control and 30 cases and divided cases into mild, moderate and heavy smokers according to no. cigarettes they were smoking daily. Pulmonary functions tests were performed by medspior instrument in a standing posture. We found that difference between predicted value and observed actual value is increased from mild smoker to heavy smokers in all the parameters like FVC, FEV1, PEFR, FEV1/FVC ratio. It suggests that tobacco smoking starts obstructive changes in the respiratory system before the onset of respiratory symptoms. Prolonged tobacco smoking may lead to respiratory diseases like emphysema, asthma and even lung cancer.
