Chronic obstructive pulmonary disease (COPD)is a progressive disease which makes one hard to breathe. The most common cause of COPD is smoking, usually higher among chronic smokers. Symptoms usually include chronic cough, difficulty in breathing (dyspnea), tachypnea, labored breathing, etc. Diagnosis is done with taking a lung function test. Management strategies include smoking cessation, use of B2 agonist inhalers and nebulizers, vaccinations, and for some patients they would need long term oxygen therapy even at home and for some, lung transplantation.
