强迫振荡技术使评估呼吸系统的机械性能与最小的合作成为可能。因此，这种方法对儿童特别有用。脉冲振荡测量法（IOS）是这种技术的一种商用版本。到目前为止，关于儿童IOS的参考值的信息有限。本研究旨在扩展IOS变量的参考值，并研究其与健康儿童身高、体重和年龄的相关性。采用脉冲振荡测量法（IOS; Jaeger，维尔茨堡，德国）对360例儿童（年龄2.1-11.1岁）进行测量。样本是基于芬兰幼儿园的儿童和瑞典小学的儿童。测定5、10、15、20 Hz时呼吸阻力（Rrs）、电抗（Xrs）、总呼吸阻抗（Zrs）和共振频率（Fr）。所有变量都与身高有关。其中大多数与体重的关系也很弱。给出了儿童（身高90-160 cm）的参考方程。
The forced oscillation technique makes it possible to evaluate the mechanical properties of the respiratory system with a minimum of cooperation. The method is therefore especially useful in children. Impulse oscillometry (IOS) is a commercially available version of this technique. There is, as yet, limited information on reference values for IOS in children. The aim of this study was to extend the reference values for IOS variables and to study their correlation with height, weight and age in healthy children. A sample (n = 360) of children (age 2.1-11.1 years) was measured by using impulse oscillometry (IOS; Jaeger, Wurzburg, Germany). The sample was based on children attending kindergarten in Finland and children attending primary school in Sweden. Measurements of respiratory resistance (Rrs) and reactance (Xrs) at 5, 10, 15 and 20 Hz, total respiratory impedance (Zrs) and the resonance frequency (Fr) were made. All variables were related to body height. Most of them were also weakly related to weight. Reference equations for children (height 90-160 cm) are presented.
