Abstract
A method of calculating body fluid and blood flow in a human or animal body using multi-frequencies alternating electrical currents, determining the tissues' multi-frequency impedance and reactance changes, calculating the body fluid, blood flow and physiological parameter. With the simultaneous measurements of body's or tissues' impedance and reactance from multi-frequencies, it is possible either to compensate for the frequency-dependencies or to find the dependencies' cross relationship, and thus measure body fluid and blood flow more accurately.
