Chronic obstructive pulmonary condition (COPD) is a prevalent, preventable, and curable illness with persistent respiratory symptoms and airflow limitation

Global Initiative for Chronic Obstructive Lung Disease (GOLD) research on chronic obstructive pulmonary condition (COPD) characterizes it as a prevalent, preventable, and curable illness with persistent respiratory symptoms and airflow limitation. airway blockage resulting in dyspnoea and air trapping when exercising airflow restriction can be attributed to smoking, ambient tobacco smoke exposure, and the patient's TB history COPD airflow restriction is largely caused by airway tightness, chronic bronchitis, or emphysema. Repeated inhalation of hazardous particles induces chronic inflammatory immune cell infiltration, tissue repair, and airway remodeling, resulting in a 4-to 40-fold increase in airway resistance and bronchiolar constriction. 20% of small airways are bronchi, with the rest being either bronchioles or alveolar ductal gaps. Flow restriction includes alveolar wall disintegration and alveolar support. The modifications worsen the rapid FEV1 fall and contribute to the...
