[Normal values of respiratory resistance in childhood (oscillation method) (author's transl)]

Normal values for respiratory resistance were determined by means of the oscillation method in 257 children and adolescents of both sexes aged 3--17 years. Respiratory resistance, measured by both the oscillatory and plethysmographic method, increased in inverse proportion to body height, body weight, body surface and age. Normal values can be estimated by means of the equation: y = 14.51--0.064X (X = hight in centimetres).
