BCM – Body Composition Monitor quick overview
Clinically important information about the body composition and the patients’ fluid status can be determined by measuring the electrical impedance response in the beta dispersion range. The complete range of the beta dispersion is sampled between 5 kHz and 1 MHz at 50 frequencies.
The physiologic tissue model is based on the different hydration properties of tissues in the human body. Physiologic differences in the distribution and amount of fluid (extracellular, intracellular and total body fluid) allow the precise determination of the three compartments Lean Tissue Mass (mainly muscle mass), Overhydration and Fat Mass. The BCM – Body Composition Monitor is also the first device on the market to distinguish muscle mass from pathologic fluid overload (see “From Technology to Therapy"). This is of special interest for the detection of malnutrition in chronic kidney disease patients.
Both the large range of measurement frequencies and the physiologic tissue model are advantages over other bioimpedance devices, which usually rely on empiric equations suited only for limited populations.
The displayed body composition and fluid balance parameters are based on a physiological model and should only be regarded as a guide. Treatment parameters and therapeutic decisions must never be made solely on the basis of the values determined by the BCM – Body Composition Monitor. The independent advice and opinion of the physician should always be
