[The significance of the flow-volume curve in pediatric lung diseases].

Even slight obstructions in small airways are detectable by means of the flow-volume curve. Therefore this method is to recommend for early diagnosis and especially in infancy. Advantages were demonstrable at the examination of different groups of asthmatics and in children with cystic fibrosis. The great sensitivity of the flow values was also shown at the bronchospasmolytic test and for provocation tests particularly. The flow-volume curve is an important routine method in pediatric pulmonology to determine the dimension and location of ventilation disorders and for follow-up studies and therapy supervision.
