title: Ten asthma pearls every primary care physician should know.
abstract: Asthma is often easily identified and effectively treated. However, presenting symptoms are variable, and many cases of asthma may not be obvious or typical. Since asthma affects about 5% of the US population, primary care physicians should be prepared to identify and manage both atypical and classic types. Atypical symptoms include disturbed sleep, chest tightness, and persistent cough without audible wheezing. Occupational factors should be suspected in all cases of adult-onset asthma. The patient's history and results of simple pulmonary function tests are useful in diagnosing, staging, and managing asthma. A beta 2 agonist delivered by metered-dose inhaler (e.g., albuterol) should provide prompt relief of most exacerbations. Inhaled corticosteroid therapy delivered via a spacer helps prevent exacerbations and has an important role in long-term control of moderate and severe asthma. If symptoms do not improve with the use of standard asthma medications, alternative diagnoses should be considered.
