COPD is defined as a disease state characterized by airflow limitation that is not fully reversible. Our study aimed at studying pulmonary function tests in patients of chronic obstructive pulmonary disease (COPD) using spirometry with the objectives of assessing their degree of airway obstruction & post-bronchodilator reversibility using spirometry. In method a total of 100 patients clinically diagnosed as COPD visiting OPD or admitted in wards of our hospital were included in the study. After careful history taking, clinical examination and routine investigations they were subjected to pre & post bronchodilator spirometry tests using computerized spirometer Helios 401. In Results Out of the 100 patients studied all had obstructive pattern of spirometry tests (FEV1/FVC <.7). 15 patients were in Global Initiative for Obstructive Lung Disease (GOLD) Stage I, 34 patients were in Stage II, 36 patients were in stage III whereas 15 patients were in stage IV of airway obstruction. In Conclusion the degree of airway obstruction in patients of COPD was easily accessed by spirometry. Most of the patients had airway obstruction in stage 2 & 3 of GOLD .There was no significant post-bronchodilator reversibility.
