Chronic obstructive pulmonary disease (COPD) is a disease characterised by slow progressive and irreversible bronchoobstruction resulting from chronic inflammation of the airways and pulmonary parenchyma, and leads to constriction of respiratory tract and limited flow of air. Risks of getting the disease are smoking and living or working in an contaminated enviroment by chemical substances. The main symptom of COPB is shortness of breath during physical exertion, and there is also coughing and reduced physical activity. Some patients in the early stages of the disease don't have symptoms or they don't recognize them, which is why the disease is mostly diagnosed in late stage of the disease. The diagnosis of COPD is made based on anamnesis, physical examination and tests, and the diagnostic test that confirms COPD is spirometry. It is important to treat the disease in early stage because of reduction of symptoms and reducing risks for exacerbation. Treatment can be pharmacologically and nonpharmacologically, but absolutely the most important part of treatment is smoking cessation. In addition to treatment, pulmonary rehabilitation is of great importance, in which the physiotherapist is an indispensable member of the team. The role of physiotherapists is an application of various physiotherapy procedures and exercises and education of patients with the aim of improving the physical and mental condition of patients. Rehabilitation includes procedures to reduce the number of symptoms of the disease, prevent complications, improve quality of life and lung function, and change life habits. In the rehabilitation process, diaphragmatic breathing exercises, expiratory exercises using the oral barrier, positional drainage, manual percussion, vibrations, inspiratory muscle training and various physiotherapeutic exercises are performed. The patient should be educated about continuing exercise after rehabilitation and changing lifestyle habits to improve quality of life.
