Bio-impedance is the manner in which a person’s body opposes the applied alternating current in a unique manner. Acquired bio-impedance data is being used for diagnosis of critical diseases condition of various systems in human body. Electrode placement on body surface to sense impedance signal for various systems is unique format for each system. This paper first part focus on design of electrical bio-impedance based acquisition system with patient identification and later part deals with visualizing, analyzing and prediction of disease condition using software tools. Impedance data from 100 patients were acquired using designed system made with surface electrodes, signal generator with variable frequency and amplitude, Microcontroller board to process acquired data. Obtained impedance values at low frequencies are a good source of cardiac related information. Data obtained from bio impedance based multi-parameter monitoring system was visualized and analyzed for the prediction of age and disease condition. The validity of this system was made using intelligent diagnosis system based on IBM SPSS computational algorithms.
