Emphysema is a form of chronic obstructive pulmonary disease that affects the tiny air sacs in the lungs, called alveoli. Over time, these structures become damaged and lose their ability to exchange oxygen efficiently. This leads to trapped air, reduced airflow, and increased work of breathing.
Although emphysema cannot be reversed, treatment can help improve symptom control, reduce exacerbations, and support a better quality of life. Pulmonary monitoring is important because symptoms may change gradually over time.
