Limb blood flow has been measured in 72 individuals by the noninvasive technique of electrical impedance plethysmography. Venous occlusion was not used. Blood flow was measured in 230 limbs in which 195 limbs were either in normal individuals or the clinically normal limbs of patients (normal limbs). Thirty-five limbs were clinically abnormal. Measurements on limbs with clinical abnormalities showed that blood flow values often fell within the limits of the normal range. However 3 cases of known vascular injury and 2 cases studied after hand surgery under tourniquet showed lowered blood flow values by comparison with the unaffected limb. A simultaneously recorded range of cardiac output and stroke volume measurements gave similar results to those obtained in a previous, unconnected study.
采用电阻抗体积描记术这一非侵入性技术，对72名个体的肢体血流进行了测量。未使用静脉闭塞法。在230条肢体上测量了血流，其中195条肢体属于正常个体或患者临床正常的肢体（正常肢体）。35条肢体存在临床异常。对临床异常肢体的测量表明，血流值常常落在正常范围之内。然而，与未受影响的肢体相比，3例已知血管损伤的病例以及2例在止血带下进行手部手术后研究的病例，其血流值降低。同时记录的一系列心输出量和每搏输出量测量结果，与之前一项不相关研究中获得的结果相似。
