Outpatient management of chronic obstructive pulmonary disease.

The outpatient management of chronic obstructive pulmonary disease (COPD) is designed to limit the decline in respiratory function over time, to relieve the symptoms and improve the patient's functional status, and to manage complications when they arise. Factors that predispose to airway inflammation, including cigarette smoking and respiratory infections, are prevented by behavioral modification programs, measures such as exercise and nutrition to improve general health, and regular vaccination. Symptoms are relieved by bronchodilator and anti-inflammatory therapy, based upon the specific needs of the patient. Hypoxemia and acute infections are treated with oxygen administration and the use of antibiotics when necessary. The management of acute exacerbations of COPD is addressed elsewhere in this symposium (ie, choice of antibiotics is not discussed here). Also, certain aspects of management, such as surgical procedures, chest physical therapy, and other aspects of pulmonary rehabilitation, are also subjects of subsequent articles in this series. Although none of these modalities, except for smoking cessation and oxygen administration, have been shown to alter the course of COPD, the careful choice of the therapeutic measures discussed here can lead to significant relief of symptoms in the patient with chronic airway obstruction.
