Equivalence of information from single versus multiple frequency bioimpedance vector analysis in hemodialysis.

Abstract

BACKGROUND In suspended cells, low-frequency current only passes through extracellular fluids, while current at higher frequencies passes through extra- and intracellular fluids. Cells in soft tissues are in contact with each other, which causes tissue anisotropy, meaning that impedance changes along different cell directions, with part of low-frequency… (More)
