title: [Evaluation of extravascular lung fluid].
abstract: The possibility of using the thermodilution technique for diagnosis of pulmonary oedema was studied in theoretical model of thermodilution between intra- and extravascular fluid spaces of pulmonary tissue as well as in acute experiments on anesthetized and immobilized dogs with hydrostatic pulmonary oedema. The intensity of thermoindicator diffusion at the "left atrium--aorta" stretch was found to depend on the degree of oedema. The following equation is suggested for calculating the pulmonary extravascular fluid volume: Vev = tev (Qao--Qpa). The thermodilution technique may be used as an independent method for diagnosis of pulmonary oedema.
