Method and device for measuring bio-impedance

摘要

The method involves detecting a bio-impedance signal using a set of electrodes (30), where a respiratory signal is derived from the bio-impedance signal by low pass filtering. A blood pulse signal is derived by high pass filtering, where the respiratory signal and the blood pulse signal are assigned to signal evaluation for determining the derived parameters. The derived parameters are evaluated in a micro controller (21), which determines a defined body condition from the totality of the derived parameters. Another set of electrodes (40) is provided for evaluation of the derived parameters. An independent claim is included for a bio-impedance measuring device.
