[Electrical properties of limb muscular tissue in acute circulatory hypoxia].
The study was undertaken to examine dispersion of the complex electric resistance and capacitive impedance of limb muscular tissue in the frequency range of 1 to 100 kHz in acute circulatory hypoxia caused by blood exfusion from the common carotid artery at 10-50% of the circulatory blood volume (CBV) at the same time local blood flow and oxygen tension in muscles were measured. Blood loss of 10-30% of CBV resulted in increased muscular tissue electric conductivity. Decompensated blood loss was characterized by a steady growth of complex electric resistance and capacitive impedance. There were the greatest changes in electric conductivity in the frequency range of 1-10 kHz.
