title: [Determination of the volume of extravascular fluid in the lungs by blood electrical resistance using a dilution method].
abstract: The theoretical basis of the method determining the volume of the extravascular lung fluid has been considered. The fluid volume is found by measuring the volume of water passing from the lung into the blood through the hyperosmotic indicator. The water volume is determined by comparing the curves of electrical resistance obtained as a result of intravenous injections of isoosmotic and hyperosmotic solutions. The electrical resistance of the blood is measured in the arterial bed. The lung fluid volume can be calculated using the parameters of the dilution curves and the equation for the crossing point.
