An instrument is described that measures limb blood flow in newborn infants by venous occlusion plethysmography. The plethysmograph is filled with air and a pneumotachygraph measures the volume displaced during venous occlusion. The response of the system is linear for flows over the range 1 to 100 ml/min and the frequency response to a square wave pressure change is 22 Hz with a 95% response time of 0.5 second. The average flow in the forearm of 10 normal newborn infants was 5.9 ml/min per 100 ml of tissue.
描述了一种通过静脉阻塞体积描记法测量新生儿肢体血流的仪器。体积描记器充有空气，呼吸流速计测量静脉阻塞期间排出的体积。该系统在1至100毫升/分钟的流量范围内响应呈线性，对方波压力变化的频率响应为22赫兹，95%响应时间为0.5秒。10名正常新生儿前臂的平均血流为每100毫升组织5.9毫升/分钟。
