To control the cardiopulmonary functioning of high risk newborn with congenital heart defects the authors apply computergenerated recording of vital parameters predominantly measured by non-invasive methods. It was found that periodic variations of the arterial partial oxygen pressure occur with occlusion of the outflow from both the right and the left ventricle, associated with patent ductus arteriosus. The authors interpret these periodic variations as intermittent contractions of the arterial duct. The pathophysiology of this phenomenon is discussed.
为控制患有先天性心脏缺陷的高危新生儿的心肺功能，作者采用计算机生成的主要通过非侵入性方法测量的生命参数记录。研究发现，在动脉导管未闭且左右心室流出道阻塞时，动脉血氧分压会出现周期性变化。作者将这些周期性变化解释为动脉导管的间歇性收缩。本文讨论了这一现象的病理生理学。
