What does COPD stand for?

Chronic Obstructive Pulmonary Disease is a term that describes a group of lung diseases, which include chronic bronchitis and emphysema. It is characterized by ongoing limitation of airflow, making it difficult for individuals to breathe, especially during physical activity. The term accurately reflects both the chronic nature of the disease and the obstruction of airflow that occurs due to airway inflammation and narrowing, as well as damage to the lung tissue. Understanding COPD is crucial for ski patrol and medical professionals, as the condition can significantly affect a person's exercise tolerance and response to high altitude and physical exertion, both of which are common in skiing and snowboarding activities. The other options presented do not accurately represent this medical condition, as they use terminology that is not recognized in medical literature.
