Alpha-1 antitrypsin deficiency and various occupational exposures are less common causes in nonsmokers. Symptoms are productive cough and dyspnea that develop over years; common signs include decreased breath sounds, prolonged expiratory phase of respiration, and wheezing. Severe cases may be complicated by weight loss, pneumothorax, frequent acute decompensation episodes, right heart failure, and/or acute or chronic respiratory failure. Diagnosis is based on history, physical examination, chest x-ray, and pulmonary function tests. Treatment is with bronchodilators, corticosteroids, and, when necessary, oxygen and antibiotics. Lung volume reduction procedures or transplantation are used in advanced disease. About 50% of patients with severe COPD die within 10 years of diagnosis. #copd #lungs #disorder Professor Armen Astvatsatryan, MD, PhD, ScD, FESC.
