Визначення рівня гідратації пацієнтів, які отримують лікування методом програмного гемодіалізу

Abstract

The thesis for the degree of candidate of technical sciences, specialty 05.11.17 – biological and medical devices and systems. – National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2017. The thesis is devoted to one of actual scientific and technical problems of modern hemodialysis - monitoring of patient hydration and developing methods for timely stopping ultrafiltration procedure when reaching the patient "dry weight". The method of determining the "dry weight" criterion which is the distribution of extracellular fluid volume into two components interstitial fluid and blood plasma volume and value compared to the removed ultrafiltrate in these components during hemodialysis developed. The mathematical model of fluid movement in the patient received the first time. electro and model processes in the patient with ultrafiltration method for bioimpedancemetry improved. Based on simulation method for determining the "dry weight" patients developed first. It is possible to determine authenticity hung reaching state normohidratotsiyi at program hemodialysis. Also practical guidelines for the application of this method in clinics created.
