Chronic bronchitis pulmonary function tests

For patients who consistently demonstrate clinical limitation in airflow, a therapeutic challenge of bronchodilators (such as albuterol aerosol) should be considered. Pulmonary function tests can be performed before and after 82-agonist aerosol administration to determine more objectively a patient s propensity to benefit from supplemental aerosol therapy. However, this laboratory assessment, often performed at times of better health, may not accurately predict a patient s potential benefit from P2 aerosols during an acute exacerbation of chronic bronchitis.
