Abstract

The responses of forced expiratory flow to inhalation of metaproterenol were evaluated in 38 patients with bronchial asthma and 52 patients with chronic obstructive pulmonary disease including asthmatic bronchitis. The “significant" bronchodilator responses were more frequent in patients with bronchial asthma than those with chronic obstructive pulmonary disease. FEV₁ and MMER were sensitive tests for evaluating the response to bronchodilator in patients, and FEV₁/FVC was not. And the data suggest that the “significant" bronchodilator response require higher percent change in lower levels of baseline lung function.
