METHOD AND DEVICE FOR HEPATIC HEMODYNAMICS ESTIMATION

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine, namely to hepatology, and aims at hepatic hemodynamics estimation. Five electrodes are installed in certain points on the patient's body to register electrical impedance of tissues. Installation of electrodes on the patient's body is followed with functional tests: record No.1 with expiratory breath-holding; record No.2 with full inspiratory breath-holding; record No.3 1.5-2 minutes after nitroglycerine intake. The specified records are used to estimate reference resistance of tissues, rheowave amplitudes and shape and analyse these data by the binary estimate system.;EFFECT: invention allows improving sensitivity and specificity of hepatic hemodynamics examination.;10 dwg, 2 tbl, 3 ex
