Уточнение эквивалентной электрической схемы организма для биоимпедансометрии при ультрафильтрации

Abstract

This article presents the problems of the use of bioimpedancemetry method (BIM) under hemodialysis. The classic theory of the liquid sectors in BIM is described. The necessity of the development of the equivalent electrical circuit (EEC) for controlling ultrafiltration during hemodialysis has been shown. As a result, the new EEC for the body patient for bioimpedancemetry method that has all the liquid sectors, whose volumes vary during the ultrafiltration is proposed. Also, in this scheme, the element corresponding to the volume deleted in "real time" excess fluid distributed in interstitial and vascular sectors has been entered. It is shown that the elements of an equivalent electrical circuit corresponding to the vascular and interstitial sectors are connected in parallel, and the constant and variable (removing liquid) part of these sectors - connected in series.
