摘要： There is provided an apparatus capable of carrying out an accurate bioelectrical impedance measurement by determining whether contact of a living body with electrodes used at the time of the bioelectrical impedance measurement is normal or not more accurately. The apparatus uses a parameter associated with a phase difference in determining the contact condition of the living body with the electrodes. As the parameter associated with a phase difference, the apparatus uses a value represented by X/R wherein R is a resistance component in a bioelectrical impedance to be measured and X is a reactance component in the bioelectrical impedance and determines that contact of the living body with the electrodes is not normal when the value of X/R is out of a determination range such as a

摘要： A living body impedance measurement apparatus is provided which measures a voltage attributed to the impedance of a living body, and separates it into a voltage attributed to a resistance component and a voltage attributed to a reactance component. Then, the voltage attributed to the resistance component, the voltage attributed to the reactance component, and resistance and reactance components of an impedance of an external reference unit are substituted into an impedance calculation formula that accounts for impedance fluctuation. A fluctuation constant is thereby calculated that is a constant for a fluctuation variable representing fluctuation caused by impedance change factors. The resistance component and the reactance component of a true impedance of the living body are then calculated based on the fluctuation constant and the measured living body impedance.
