Based on the inquiry of 252 patients an investigation was carried out concerning the frequency of manifest bronchial obstruction in dependence on the bronchial hyperreactivity. Patients with bronchial hyperreactivity showed more frequently with a high significance as well a decrease in the FEV1 as an increase of resistance. Therefore in dependence on the occurrence of a manifest bronchial obstruction also the probability of a simultaneous presence of bronchial hyperreactivity increases. The results are important for understanding the functional dynamics of the bronchopulmonary system, especially the evocation of dyspnea by irritation of the respiratory tract.
