The electrocapacitance plethysmograph was utilized to measure peripheral blood flow and venous distensibility in 17 newborn infants and 20 adults. Measurements were made in the upper and lower extremities in each subject under identical environmental conditions. Blood flow in the forearm and calf were found to be significantly higher in infants than adults. In infants there were no significant differences in the blood flow between the upper and lower extremities. In contrast, in the adults, the blood flow was significantly higher in the upper than in the lower extremities. Similarly, venous distensibility was observed to be higher in infants than in adults. While no significant differences were observed in the venous distensibility between the upper and lower extremities in infants, the venous distensibility was found to be higher in the forearm than in the leg in adults.
使用电容式体积描记器测量了17名新生儿和20名成年人的外周血流和静脉扩张性。在相同环境条件下，对每个受试者的上肢和下肢进行了测量。发现婴儿前臂和小腿的血流明显高于成年人。婴儿上肢和下肢的血流没有显著差异。相比之下，成年人上肢的血流明显高于下肢。同样，观察到婴儿的静脉扩张性高于成年人。虽然婴儿上肢和下肢的静脉扩张性没有显著差异，但发现成年人前臂的静脉扩张性高于腿部。
