Chronic obstructive pulmonary disease (COPD) is airflow limitation caused by an inflammatory response to inhaled toxins, often cigarette smoke. The cardinal feature of COPD is airflow limitation, which is due to: - loss of alveoli and bullae development with loss of elastic recoil and air trapping from narrowed airways, - poor ventilation through narrow airways and poor diffusion and abnormal perfusion. Test. - reduction in tethering of small airways, - permanent, abnormal airspace enlargement. Updated July 19, 2019. Inflammation in COPD predominantly due to: - increased lung oxidants (Hydrogen peroxide, nitric oxide) generate by smoking, - smoking (inhaled noxious stimuli_ leads to imbalance between protease and antiprotenase by causing protease release from neutrophil and macrophage, - neutrophil elastase release out balances AAT.
