Abstract
The specific resistance (¿) of canine blood, having a hematocrit (H) range extending from 0 to 70 percent, was measured at 37°C and 25 kHz using a variable-length conductivity cell connected to a constant-current impedance bridge. A least-squares exponential fit for the experimentally determined dataprovided the relationship ¿= 56.8e0.025H with a correlation coefficient of 0.989. The data obtained were also fitted to the Maxwell-Fricke equation; an excellent fit was obtained in the range of 0-50 percent hematocrit using a form factor of 2.5.
