AIM OF THE STUDY: Smokers with suspected COPD seek medical attention when they become dyspnoeic on mild to moderate exertion, but by than half of the ventilator reserves are lost irreversibly. Hence it seems logical to diagnose COPD early before development of significant symptoms. Since smoking cessation in COPD is found to reduce rapid decline of ventilator function in smokers and to make an attempt to quit smoking in south Indian population. MATERIALS AND METHODS: Patients attending outpatient department at MGM Govt. Hospital attached to KAPV Govt. Medical College, Tiruchirappalli. EASY ONE spirometer. TYPE OF STUDY: Unicentric Prospective description study. USEFULNESS OF THE STUDY: Chronic obstructive pulmonary disease (COPD) is a major case of chronic morbidity and mortality. Third leading cause of death in 2020Smoking cessation will improve quality of life and decrease the morbidity and mortality. CONCLUSION: 1. The most common age of first smoking is 18 years and all participants had started smoking by 26 years. 2. The youngest age of first smoking is at 16 years 3. The age of first smoking does not have significance with airflow limitation 4. The most common age group found is 39-49 years 5. The most prevalent BMI is 18.5-24.9 and does not have significance in respect to airflow obstruction . 6. SI has significant negative correlation with FEV1/FVC and Significant positive correlation coefficient with age. 7. The quantum of smoking correlates with severity of airflow obstruction as indicated by SI 8. There is 17.8% of asymptomatic smokers have airflow limitation in the form of obstructive lung disease. 9. There is 61.29% of asymptomatic smokers had mild COPD and 38.7% had moderate COPD as per GOLD guidelines 10. The FEV1/FVC ratio as a screening tool to detect the presence of COPD in asymptomatic smokers is established 11. Handheld in office spirometry is useful for screening the smokers for presence of airflow obstruction before significant symptoms. 12. MEF 25-75 also has significant positive correlation coefficient with FEV1/FVC ratio and significant negative correlation with SI
