In newborn infants with varying hematocrit values the submaximal blood flow has been studied by the use of strain gauge plethysmography under standardized conditions. Submaximal flow was defined as the flow obtained after 4 minutes of suprasystolic occlusion. With increasing hematocrit there was a decreasing maximal flow. Capillary filtration coefficient seemed to decrease with increasing hematocrit. The relation between circulatory failure in newborns due to abnormally high hematocrit and low capacity to increase blood flow upon demand has been discussed.
在不同血细胞比容值的新生儿中，已在标准化条件下使用应变片体积描记法研究了次最大血流量。次最大流量定义为收缩期上压闭塞4分钟后获得的流量。随着血细胞比容的增加，最大流量降低。毛细血管滤过系数似乎随着血细胞比容的增加而降低。已经讨论了由于血细胞比容异常高导致的新生儿循环衰竭与按需增加血流量能力低之间的关系。
