Chronic obstructive pulmonary disease (COPD) is estimated to affect 32 million persons in the United States and is the third leading cause of death in this country (Mosenifar Z. Chronic Obstructive Pulmonary Disease (COPD). In: Oppenheimer JJ, editor. Medscape. Updated: Jun 03, 2022. https://emedicine.medscape.com/article/297664-overview . Accessed 7 Apr 2024). Patients typically have symptoms of chronic bronchitis and emphysema, but the classic triad also includes asthma or a combination of the above. COPD is a common and treatable disease characterized by progressive airflow limitation and tissue destruction. It is associated with structural lung changes due to chronic inflammation from prolonged exposure to noxious particles or gases, most commonly cigarette smoke. Chronic inflammation causes airway narrowing and decreased lung recoil. The disease often presents with cough, dyspnea, and sputum production symptoms. Symptoms can range from being asymptomatic to respiratory failure.
