The quantity of blood measured by electrical impedance plethysmography is defined by its resistive effect in parallel to the resistance of other tissue of the segment. By substitution of this parallel resistive value, together with data relative to the resistivity of blood and the length of the segment in the formula for the volume of an electrical conductor, we are able to derive the volume of the pulse in cubic centimeters. It follows that the volume displaced from the venous reservoir and the rate of refilling of the venous reservoir of an extremity may also be determined quantitatively.
