    • Abstract:
      A model of a limb part represented as a multilayer cylindrical conduction section is considered. The impedance is measured by means of four electrodes, and the exact and approximate expressions for the impedance are derived. With the expressions, one can calculate the value of the pulse blood flow. Various factors affecting the measurement accuracy such as skin conditions, local depths of major vessels, and relative electrode positions are analyzed. Recommendations for the choice of the electrode spacing are given to calculate the pulse and specific blood flow depending upon dimensions of the body part under study, the accuracy being not less than the preset value.
