Predicting Response to Bronchodilator Therapy in Chronic Obstructive Pulmonary Disease

Predicting Response to Bronchodilator Therapy in Chronic Obstructive Pulmonary Disease Abstract Although the diagnosis and assessment of airflow obstruction is accomplished by pulmonary function test measurements (PFTs),1 it has recently become clear that comparing PFTs before and after bronchodilator (BD) is of limited value either to (1) separate chronic obstructive pulmonary diseases (COPD) from asthma2 or (2) predict the long-term clinical response of patients with COPD to BD therapy.3 The article by Guyatt et al4 in this issue of the Archives adds to the growing evidence that PFTs before and after BD are indeed imperfect guides to predicting clinical response to BD therapy in COPD.
