  • Title: [Determination of hemodynamic parameters by blood electrical resistance using a dilution method].
    Author: Kislukhin VV, Krivitskiĭ NM.
    Journal: Med Tekh; 1987; (1):3-6. PubMed ID: 3550359.
    Abstract:
    The theoretical basis and the experimental data of the hemodynamic parameter determination method have been described. The cardiac output and the circulating blood volume have been determined using intravenous injections of two solutions with different electrical resistance. A formula for blood electrical resistance was proposed. Tolerances for isoosmotic solutions were made. A system of three equations was made up on the basis of the results of two injections of solutions with different electrical conductance. From these equations blood characteristics, cardiac and circulating blood volumes can be obtained. Isoosmotic solutions of glucose and sodium chloride were used as indicators in treadmill tests with circulating blood. The measurement error practically didn't depend on the electrode type (either along or across the flow).
