Abstract
In a group of 50 children with a negative case- history as regards airways and lacking acute respiratory disease, the authors assessed the resistance of the airways on a whole-body plethysmograph and by using the interruptor method on a Bronchoscreen (Jaeger) apparatus. The authors found a satisfactory correlation of the two methods (r = 0.7). When relating the resulting values of resistance to height, greater differences were found between the two methods in younger children; with increasing height the differences disappear. For the relationship of the resistance assessed by the interruptor method and height in our group a Rint regression equation was calculated [kPa/(l/s)] = -0.00765 X height (cm) + 1,565.
