Diagnostic efficiency of bioimpedance measurements

More than one century ago started the interest of researchers for bioimpedance measurements, "in vitro" or "in vivo". In this short overview, we shall consider only "in vivo" applications by use of surface self-adhesive electrodes. Today, bioimpedance measurements reveal an important interest as one method for noninvasive exploration of tissue structure and properties or physiologic events, i.e. "static" or "dynamic" human organism properties. In addition to noninvasivity, measurements and required instrumentation is simple, not expensive and imposes not the demands for highly skilled staff. One of the main problems, when bioimpedance measurements are considered, is the reliability of results. This means problem of elimination the effect of electrode impedance, the repeatability of measurements and establishing the criterion of normality for particular measurement procedures. This paper presents also the results of the research performed on patients with ischemic syndromes in lower legs.
