Recognition and management of exercise-induced bronchospasm.
Exercise-induced bronchospasm is an obstruction of transient airflow that usually occurs five to 15 minutes after physical exertion. Although this condition is highly preventable, it is still underrecognized and affects aerobic fitness and quality of life. Diagnosis is based on the results of a detailed history, including assessment of asthma triggers, symptoms suggestive of exercise-induced bronchoconstriction, and a normal forced expiratory volume at one second at rest. A trial of therapy with an inhaled beta agonist may be instituted, with the subsequent addition of inhaled anti-inflammatory agents or ipratropium bromide. Nonpharmacologic measures, such as increased physical conditioning, warm-up exercises, and covering the mouth and nose, should be instituted. If symptoms persist, pulmonary function testing is warranted to rule out underlying lung disease.
