[Oscillatory impedance measurement of the respiratory tract in children].
The author reports on his own experiences with monofrequent and polyfrequent oscillatory impedance measurements of the respiratory tract in childhood. The monofrequent oscillatory process was tested in a total of 10 trials in respect of its suitability to estimate the complex respiratory resistance in the region of lower and upper respiratory tract in a total of 1071 children most of whom were healthy, some children having a diseased respiratory tract, between 3 and 19 years of age. In 268 children the nasal respiratory resistance was measured, in 803 the bronchial respiratory resistance. The polyfrequent oscillation method was compared in 2 examinations with body plethysmography and spirometry in respect of its discriminatory powers between healthy subjects and children suffering from asthma, and in respect of its suitability to prove bronchial hypersensitivity on carbachol provocation, using 93 healthy and 81 asthmatic children. The results of the 12 examinarions are surveyed and discussed.
