10 physiological and 16 pathological--mostly premature--newborn were investigated by means of cardiorespirography. For heart frequency records of physiological newborn the undulatory zone (by disturbance or waking) and the narrowed undulatory zone (by sleeping) were typical, while in pathological newborn the silent zone predominated. In physiological newborn the respiratory curves type I and type III were typical; in the pathological ones types II, IV und V were most frequent. No correlation was found between pathologocial findings on cardiorespirograms and the clinical diagnosis. Nevertheless, oscilatory types of curves correlate well with pH values of blood.
通过心肺描记法对10名生理状态的新生儿和16名病理状态的新生儿（大多为早产儿）进行了研究。对于生理状态新生儿的心率记录，波动区（因干扰或清醒）和变窄的波动区（因睡眠）较为典型，而病理状态新生儿中则以静息区为主。生理状态新生儿中，I型和III型呼吸曲线较为典型；病理状态新生儿中，II型、IV型和V型最为常见。心肺描记图的病理结果与临床诊断之间未发现相关性。然而，曲线的振荡类型与血液的pH值有很好的相关性。
