What does COPD stand for?

Chronic Obstructive Pulmonary Disease is the correct term represented by the acronym COPD. It is a progressive lung disease characterized by increasing breathlessness. The term emphasizes that this condition involves chronic inflammation and obstruction of airflow in the lungs, primarily due to long-term exposure to irritants such as cigarette smoke, air pollution, and occupational dusts. Understanding the full name helps in recognizing its implications for patient management and treatment strategies, including the use of bronchodilators and inhalers to alleviate symptoms and enhance quality of life. The other options provided do not accurately reflect the medical terminology or the characteristics of the disease, which is why they do not represent the correct answer.
