Discussion of clinical application of bioelectrical impedance / 肠外与肠内营养

ABSTRACT

Bioelectrical impedance analysis(BIA)measures the body composition and its change by the electric feature of the extracellular fluid and intracellular fluid.It has been widely used for its noninvasiveness, convenience and accuracy, especially in population epidemiology and clinical monitoring.We aim to review the advantages and shortcomings,and try to discuss about the application of this technique and its potential.
