Abstract
Background: Smoking is one of the significant contributing risk factors for chronic obstructive pulmonary disease (COPD) and increases risk of death in cardiovascular and respiratory disorders. Aims and Objectives: This study was planned to see the influence of cigarette smoking on forced expiratory volume in first second (FEV1). Materials and Methods: FEV1 of 50 male moderate smokers (asymptomatic) and 50 healthy male non-smokers of age and height matched was recorded using RMS Helios 401 Spirometer. Results: The reduction of FEV1 in smokers was statistically significant. Conclusion: Smoking is preventable cause of COPD. Reduced FEV1 value in smokers is an indicator of risk factor for the development of COPD which can be prevented by early identification and proper counseling in asymptomatic smokers. This is important to prevent future complications.
