Abstract
Monitoring the hydration and/or nutrition status of a patient by bioimpedance. A bioimpedance method and device that makes use of a refined model by which the conductivity contributions from intracellular tissues can be taken better into account to enable an improved assessment of the body composition of a patient with increased accuracy. The intracellular volume (ICV) of a patient is determined by determining an intracellular electrical resistance Rmix of the patient and deriving the intracellular volume ICV using Rmix by taking into account that a cell of a kind of tissue contributes differently to the electrical resistance Rmix of the intracellular volume ICV compared with a cell of a second kind of tissue. The application also relates to a device for carrying out the method according to the invention and to a computer program product to be used on such a device.
