DEVICE AND METHOD FOR THE DETERMINATION OF DRY WEIGHT BY CONTINUOUS MEASUREMENT OF RESISTANCE AND CALCULATION OF CIRCUMFERENCE IN A BODY SEGMENT USING SEGMENTAL BIOIMPEDANCE ANALYSIS

摘要

A method and device for continuously calculating the circumference of a body segment is based on the continuous measurement of the extracellular resistance of the body segment. Also disclosed is a method and device for determining the dry weight of a dialysis patient wherein the time at which the dry weight of the patient has been achieved is identified as the time at which the patient's normalized resistivity as a function of time (?SUBN/SUB(t)) is greater than or equal to a minimum level of normalized resistivity in healthy subjects (?SUBN/SUB,H).
