The study analyzed the changes in the shape of the flow-volume curve after fenoterol (Berotec) inhalation in school age healthy children. Significant increase of FEF25-75%, FEF50%, FEF25% values were seen. The authors demonstrated that bronchodilatation was not related to sex, height, weight and children's age, but it's value is indirectly proportional to the at-rest state of the airways. It seems, basing on results of this study, that FEV1 and FEF25-75% are the best indexes of dilatation tests. Increases of 10% and 30% are significant of bronchodilatation.
