title: [Evaluation of bronchial resistance in healthy children].
abstract: Pneumotachography was used to examine bronchial resistance (BR) in 169 healthy children aged 6 to 16 years. A negative correlation was established between BR and the height, body weight and age. Regression equations were elaborated for computing due magnitudes of BR. The percentile distribution of BR makes it possible to refer children with BR from 130 to 140% of the due magnitude to the risk group and to consider the BR magnitudes exceeding 140% as pathological. The reproducibility of BR was determined. In view of this fact it is suggested that during pharmacological tests, the change of BR by more than 33% of the due magnitude should be regarded as significant.
