Respiratory Symptom Evaluation in Adults: Wheezing

Wheezing is a common presenting concern in the primary care setting, but its etiology can be elusive. Wheezing is associated with many disease processes, but most commonly, asthma and chronic obstructive pulmonary disease. Initial tests for wheezing typically include a chest x-ray and pulmonary function testing with bronchodilator challenge. Advanced imaging to evaluate for malignancy should be considered in patients older than 40 years with a significant history of tobacco use and new-onset wheezing. A trial of short-acting beta agonists can be considered while awaiting formal evaluation. Because wheezing is associated with reduced quality of life and increased health care costs, it is essential to develop a standardized evaluation of this common concern and expeditiously manage symptoms.
