Chronic Obstructive Pulmonary Disease: Diagnosis and Management.
Chronic obstructive pulmonary disease (COPD) affects nearly 6% of Americans. Routine screening for COPD in asymptomatic adults is not recommended. Patients with suspected COPD should have the diagnosis confirmed with spirometry. ⋯ Mucolytics, antitussives, and methylxanthines do not improve symptoms or outcomes. Long-term oxygen therapy improves mortality in patients with severe resting hypoxemia or with moderate resting hypoxemia and signs of tissue hypoxia. Lung volume reduction surgery reduces symptoms and improves survival in patients with severe COPD, whereas a lung transplant improves quality of life but does not improve long-term survival.
