The applicability of bodyplethysmography in children often fails by the anxiety of sitting alone in the closed plethysmograph cabin. By comparing measurements however it is proved that the results of airway-resistance and thoracic gas volume are not changed in any way, if an adult person accompanies the child inside the cabin. The assumption being essential for a correct measurement are discussed.
体容积描记法在儿童中的应用常常因儿童独自坐在封闭的体容积描记仪舱内产生焦虑情绪而失败。然而，通过对比测量结果证明，如果有成年人在舱内陪伴儿童，气道阻力和胸腔气体容积的测量结果不会有任何改变。文中还讨论了正确测量所必需的假设条件。
