88 children of school age suffering from bronchial asthma have been examined in the setting of the pulmonological department of the Regional Children’s Clinical Hospital. Bronchial lability in response to dosed running and salbutamol inhalation has been studied in all the patients. It has been demonstrated that the indices of bronchial hypersensibility are essentially higher both at the expense of bronchodilatation and bronchospasm in patients with bronchial asthma of physical exertion. The index of bronchodilatation more than 17% and the index of bronchial lability more than 42% with high specifity and a predicted value of a positive result confirm the presence of exercise-induced asthma in a child.
