Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. x�+� � | People with COPD have less air flowing in and out of the airways. ��� endobj It is essential to note the warning signs of COPD and consult a doctor if they appear. This phenomenon is called air trapping and causes the lungs to hyperinflate. An infection in the airways or elsewhere the body usually triggers an exacerbation. endobj The extent of airflow limitation is determined by the severity of inflammation, development of fibrosis within the airway and presence of secretions or exudates. This is because the bronchi (airways) are partially blocked due to mucus, inflammation, and lung damage.
