摘要：

A method is presented for monitoring the relative variation of extracellular and intracellular fluid volumes using a multifrequency impedancemeter and the Cole-Cole extrapolation technique. If is found that this extrapolation is necessary to obtain reliable data for the resistance of the intracellular fluid. The extracellular and intracellular resistances can be approached using frequencies of, respectively 5 kHz and 1000 kHz. but the use of 100 kHz feads to unacceptable errors. in the conventional treatment the overall relative variation of intracellular resistance is found to be relatively small.
