Abstract

Pulmonary function tests are non-invasive diagnostic test that provide measurable feedback about the function of lungs. An assessment of lung volumes, capacities and flow rates provide specific information for clinical diagnosis and research purposes. Smoking is an addiction which affects the normal life, body and organ system as whole. Passive Smoking is defined as exposure of non smoker to tobacco smoke in the environment. Second hand tobacco smoke is the precursor of the primary active smoke from the smoker. Second hand tobacco smoke is believed to be more harmful than the primary smoke from the active smoker. The potency and health effects of second hand smoke involved the smell of secondhand smoke being an allergen affecting the respiratory system. The effects of passive smoking on respiratory system and lung function test warrants documentation.
Aims and Objective: To evaluate the effect of passive smoke on lung function test among women exposed for ten years.
Materials and Methods: The study was conducted on fifty females in the age group of 30-60 years who were exposed to passive smoke for ten years. An identical number of age matched females who were not exposed to cigarette smoke at home served as controls. The lung function parameters recorded were FVC, FEV1, FEV1/FVC%, PEFR, MVV and FEF25-75%
Results: The study demonstrated decline in mean values of FVC, FEV1/FVC%, MVV and FEF25-75% in female subjects but the difference in the mean values when compared with controls was found to be statistically insignificant. The mean values of FEV1 and PEFR was less in female subjects and the difference in the mean values was statistically significant. The study demonstrated decline in the expiration of FVC in first second and decline in maximum flow rate during forceful expiration that conforms to obstructive pattern of lung changes in females exposed to chronic passive smoke.
Conclusion: Any significant decline in lung functions in females being most vulnerable in household, with time merits attention as they indicate likely morbidity in the event of continuing exposure to the offending agent.
