Chronic obstructive pulmonary disease: clinical signs and infections.

摘要

Chronic obstructive pulmonary disease (COPD) is a pathological condition that involves excessive production of mucus, chronic cough and inflammatory changes leading to airway limitation. The most common cause of COPD is cigarette smoking. COPD can be categorized into either chronic bronchitis or emphysema; both conditions can be differentiated by age and the production of copious, tenacious sputum. Patients with COPD are susceptible to pulmonary infections of bacterial or viral origin. Nurses should be aware of the subtle differences in conditions and the usefulness of antibiotics in the treatment of acute bacterial exacerbations of chronic bronchitis.
