Successful body plethysmographic examination of infants and toddlers can now be performed by means of a special baby plethysmograph which is commercially available (Fa. Jaeger, Würzburg, Fed. Rep. of Germany). The apparatus is equipped with a heated rebreathing system and manipulation ports. Examinations require paying attention to certain potential sources of error: the consequences of necessary sedation; possible undefined leaks due to non-airtight manipulation ports; the influence of irregular breathing or increasing hyperventilation; the effect of nasal resistance; the large variation in total airway resistance; problems in the quantitative evaluation of box pressure/flow curves and curve form analysis. Careful handling can overcome all these difficulties. From the clinical point of view, body plethysmographic examination is just as important for infants and toddlers as for schoolchildren and adults.
现在可以通过一种市售的特殊婴儿体积描记器对婴幼儿进行成功的人体体积描记检查（德国联邦共和国维尔茨堡的耶格公司）。该设备配备了加热的再呼吸系统和操作端口。检查时需要注意某些潜在的误差来源：必要镇静的后果；由于操作端口不气密可能导致的未定义泄漏；不规则呼吸或过度通气增加的影响；鼻阻力的影响；总气道阻力的巨大变化；箱内压力/流量曲线定量评估和曲线形态分析中的问题。谨慎操作可以克服所有这些困难。从临床角度来看，人体体积描记检查对婴幼儿和学龄儿童及成年人同样重要。
