Pathophysiology the above pathogenic mechanisms result in the pathological changes found in copd these in turn result in physiological abnormalities—mucous hypersecretion and ciliary dysfunction, airflow obstruction and hyperinflation, gas exchange abnormalities, pulmonary hypertension, and systemic effects. Chronic obstructive pulmonary disease, or copd, refers to a group of diseases that cause airflow blockage and breathing-related problems it includes emphysema and chronic bronchitis copd makes breathing difficult for the 16 million americans who have this disease.
