OBJECTIVE: To study the various spirometry ndings and look for its association with smoking history and use of biomass fuels.
METHODS: Spirometry ndings of 375 patients who attend Respiratory medicine OPD from year 2017- 2019 were studied.
RESULTS: Out of 375 patients, 95 patients were diagnosed as COPD, 62 as bronchial asthma, 149 had normal spirometry and 69 had restriction.
CONCLUSION: In this study we concluded that spirometry plays an intergral role in the diagnosis of bronchial asthma, COPD and restrictive
lung diseases. It gives an overview of the decline of lung function with increasing age, smokers, occupational lung exposures, family history of
bronchial asthma. Restrictive patterns were most commonly seen in patients who came for pre operative evaluation.
