Pulmonary rehabilitation represents a modern therapeutic approach of respiratory diseases, with a multidisciplinary character, including: physical training, therapeutic education, psychosocial counseling, and nutritional approach. Pulmonary rehabilitation addresses to any patient suffering from pulmonary pathology whose quality of life is affected by the respiratory symptoms, regardless of the degree of functional impairment. This article is an analysis of evidences from the medical literature on outcomes of rehabilitation programs conducted in various lung diseases. The main indication of pulmonary rehabilitation is the chronic obstructive pulmonary disease - COPD (stable state and exacerbation) in which most studies were carried out. Pulmonary rehabilitation in patients with other respiratory pathology has its reason in the pathophysiological changes that they undergo (impaired lung function and gas exchange, muscle atrophy and deconditioning etc.) leading to symptoms, lower exercise tolerance and decrease daily physical activity, all of which ultimately result in impaired quality of life. The role of rehabilitation is reviewed in the following diseases: post-surgical lung volume reduction for emphysema, asthma, bronchiectasis, interstitial lung disease, cystic fibrosis, lung cancer, neuromuscular disease, intensive care, obstructive sleep apnea, pulmonary hypertension, post-tuberculous sequelae, lung transplantation.
