Abstract :
Blood resistivity is an important quantity which value influences the results of various methods used in the study of heart and circulation. In this paper, the relationship between blood resistivity and velocity of blood flow was evaluated and analyzed based upon a probe using six-ring electrodes and a circulatory model. The experimental results indicated that the change in blood resistivity was only ±1.1% when the velocity of blood flow changed from 2.83 cm/s to 40 cm/s and it rose to 23% when the velocity was lower than 2.83 cm/s
