Treatment of Acute Exacerbations in Chronic Obstructive Pulmonary Disease. Management of a chronic obstructive pulmonary disease (COPD) exacerbation begins with an accurate diagnosis. Although more than 80% of exacerbations are managed on an outpatient basis, hospitalization is all too common and associated with considerable health care costs and mortality. Irrespective of the site of treatment, the treatment modalities are the same. Noninvasive ventilation has greatly decreased the mortality in exacerbations that require ventilatory support. Across the range of exacerbation severity, treatment failure and relapses are frequent, and should be carefully evaluated. New therapeutic options to address infection and inflammation in COPD are needed to improve the outcome of exacerbations.
