title: [Noninvasive method of determining the cerebral blood flow circulation rate and its correlations with cardiac minute volume].
abstract: A method is suggested for noninvasive determination of the cerebral circulation rate and its correlations with the cardiac output. It is based on the metrological possibilities of tetrapolar rheoencephalography in correlation with chest (transthoracic) rheography. The percentage of cerebral circulation rate in relation to the cardiac output measured by this method (Ic/o) characterizes the direction and value of compensatory blood redistribution in various hemodynamic situations, while the absolute values of cerebral circulation rate (Cm, in millilitres per minute) and their relation to the proper values (Cm. in % of proper values) make it possible to appraise the afficacy of the compensatory shifts in each individual case. The method may gain wide use in the clinic for indirect appraisal of the condition of the cerebral circulation.
