METHOD AND DEVICE FOR INSPECTING STATE OF CARDIO-VASCULAR SYSTEM AT MECHANICAL DAMAGE Russian patent published in 2007 - IPC A61B5/02 

FIELD: medicine.

SUBSTANCE: method and device can be used for determining heaviness of damage at gunshot wound, different traumas, and long-time compression syndrome. Gunshot wound is caused experimentally and systolic and diastolic arterial pressure is registered in left ventricle of heart as well as electrocardiogram, pulse-gram and heart rhythm. Central hemodynamics' factors are calculated; minute volume of bigger and smaller circles of blood circulation, total peripheral vessel resistance, central venous pressure. If cardio-vascular system is heavily damaged, the following phases of reacting on gunshot wound are selected: first phase is characterized by short time increase in all factors of central hemodynamics; second phase is characterized by reduction in systolic arterial pressure, of heart beat frequency and central venous pressure while diastolic pressure keeps stable; third phase is characterized by increase in systolic and central venous pressure while diastolic pressure is reduced and heart beat frequency increases accompanied by development of hypervolemic hyperkinetic-type damage complicated by hyper-hypodynamic vascular dehydration, characterized by quick entry of liquid into vascular sector at which bigger and smaller blood circulation circles equal to more than 5 liters; fourth phase is characterized by abrupt reduction in systolic arterial pressure and central venous pressure while diastolic arterial pressure and heart beat frequency rate abruptly increase accompanied by development of hypervolemic hyperkinetic-type critical volemic damage accompanied by hyperdynamic vascular dehydration, characterized by quick exit of liquid out of vascular sector, at which exit smaller minute volume circle is less than 5 liter and the bigger one is more than 5 liter. Fifth phase, terminal one, is characterized by abrupt drop in both components of arterial pressure and central venous pressure accompanied by increase in heart beat frequency range when hypovolemic hypokinetic-type development of critical volemic damage with hyperhydrodynamic vascular dehydration at which dehydratation the smaller and bigger minute volumes equal to less than 5 liters. Device for realization of the method is also presented. Method and device allow providing complex estimation of heaviness of damage while taking parameters of central hypodynamics, changes in electrocardiogram, and state of blood circulation in damaged tissues and energy of destroying factor into account.

EFFECT: improved efficiency of operation.
