The changes in blood resistivity with haematocrit and temperature
The temperature dependence of the resistivity of blood samples with haematocrits from 16 to 52.5% has been investigated over the temperature range of 22 degrees ot 40 degrees C at a frequency of 100 kHz. The resistivity of whole blood increased with an increase in haematocrit and a decrease in temperature. The data fitted the relationship: Pohm-cm=(6.272 Hct + 75.176) - (0.104 Hct + 1.467) tC weree Hct is the percentage haematocrit.
