Abstract

Comparison of electrical impedance measured in vivo with the in vitro impedance of several types of tissue shows that the former is mainly determined by the presence of striated muscle in the region between the electrodes. This means that fluid shifts occurring during hemodialysis, in the blood or any tissue other than skeletal muscle, do not affect tissue impedance. This implies that measurement of tissue impedance as a means of monitoring the process of hemodialysis lacks a model for a reliable interpretation in terms of fluid balance.

摘要

体内测量的电阻抗与几种组织的体外阻抗比较表明，前者主要由电极之间区域的横纹肌的存在决定。这意味着血液透析过程中发生在血液或骨骼肌以外的任何组织中的液体转移不会影响组织阻抗。这意味着将组织阻抗测量作为监测血液透析过程的一种手段缺乏一个根据液体平衡进行可靠解释的模型。
