Pulmonary Rehabilitation in the Management of Chronic Lung Disease.

Pulmonary rehabilitation is a core component of management of patients with chronic lung disease that have exercise or functional limitations. Causes of these limitations are manifold but include loss of skeletal muscle mass, power and endurance, diminished respiratory capacity owing to respiratory muscle weakness, inefficient gas exchange, and increased work of breathing, and impaired cardiovascular functioning. Besides physical limitations, patients with chronic lung disease have high rates of depression and anxiety leading to social isolation and increased health care use. Pulmonary rehabilitation uses a comprehensive and holistic approach that has been shown to ameliorate most effects of chronic lung disease.
