The symptoms of COPD can be treated; however, the airflow limitation is not fully reversible. Cigarette-associated noxious agents injure the airway epithelium and drive the key processes that lead to specific airway inflammation and structural changes [].Once these agents are removed, repair processes should, ideally, bring the airways back to their normal structure and function.

Effect of hyperinflation on inspiratory function of the diaphragm. They show that the earliest manifestation of chronic obstructive pulmonary disease (COPD) is an increase in residual volume suggesting that the natural history of COPD is a progressive increase in gas trapping with a decreasing vital capacity (VC). This leads to airflow limitation and the destruction and loss of alveoli, terminal bronchioles and surrounding capillary vessels and tissues, which adds to airflow limitation and leads to decreased gas transfer capacity (Fig 1). pp 57-63 | Reassessment of inflammation of airways in chronic bronchitis. 0000262331 00000 n 0000005384 00000 n 112 0 obj <>stream Repeated injury and repair leads to structural and physiologic changes.
