Abstract

This study analyzes the effect of orthostatic fluid shift caused by body postural changes on the reliability and stability of bioelectrical impedance. It has been found that following a fluid distribution perturbation caused by postural changes, impedance values change for a period of time that can be longer than the measurement time. Based on these preliminary measurements, it is recommended that new measurement protocols for bioelectrical impedance be developed in order to minimize perturbations on existing fluid distribution, thus increasing the reliability of bioelectrical impedance data.
