DEVICE AND METHOD FOR MEASURING SEGMENTAL BIOIMPEDANCE OF DIALYSIS PATIENT

摘要

PROBLEM TO BE SOLVED: To provide a precise, easily used and operator-independent method and system for determining the hydration state of a dialysis patient, identifying or predicting the dry body weight of such a patient, and calculating the amount of fluid that should be removed during a dialysis session.SOLUTION: The present invention includes a method of determining the dry body weight of a patient undergoing dialysis by means of segmental bioimpedance analysis. In preferred embodiments, dry body weight is determined by comparison with the bioimpedance values of normal subjects or by monitoring changes in bioimpedance during dialysis. One embodiment of the present invention is a device for determining dry body weight during dialysis.SELECTED DRAWING: Figure 2
