Emphysema What is emphysema? Chest. 2015;192(6):695- The poor airflow is the result of breakdown of lung tissue (known as emphysema), and small airways disease known as obstructive bronchiolitis. Chronic Bronchitis is one of the conditions that cause COPD. It is diagnosed if a patient has a cough and sputum production for 3 months in 2 consecutive years. Note the subpleural, thin-walled, cystlike appearance (Correa da Silva, 2001). (COPD) is a lung disease characterized by airway obstruction due to inflammation of the small airways.
