Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease 2.1 Definition and terms universally accepted for a group of diseases characterized by -------------------------- There is no terminology. The definition of airway obstruction is completely reversible (Snider, 1996). There are several points to consider. The first result is the use of the term "chronic obstructive pulmonary disease" (COPD). This is considered inaccurate, not a real disease, but a group of diseases.

Chronic bronchitis and emphysema are considered by many as being variants of chronic obstructive pulmonary disease and are thought by many investigators to be part of the progression of chronic obstructive pulmonary disease. Chronic bronchitis is defined as a chronic cough that lasts more than 3 months for 2 consecutive years. Colon excision such as nicotine replacement therapy, β-2 agonist, chronic obstructive pulmonary disease drug such as anticholinergic drug (bronchodilator), combination drug using steroid and long-acting bronchodilator, mucolytic drug, oxygen therapy Surgery such as surgery, lung volume reduction surgery and lung transplant

The main cause of chronic obstructive pulmonary disease is smoking or exposure to tobacco smoke. It is estimated that 90% of the risk of developing chronic obstructive pulmonary disease is related to tobacco smoke. Smoke is also a passive smoke (cigarette smoke inhaled by non smokers after being exhaled by smokers). Damage to lung tissue over time leads to physical changes in lung tissue and airway obstruction by viscous mucus. Tissue injury in the lung results in reduced compliance (elasticity or ability to expand the lung tissue). The fact that the elasticity of the lung is reduced means that oxygen in the air can not reach the alveoli (alveolus) through an obstacle (eg, thick mucous plug) and oxygen and carbon dioxide exchange occur in the lungs It means. Therefore, the person first showed a particularly difficult difficulty, coughing to remove obstacles such as mucus and then breathing.
