Patent ID: 8157848

Claim:
A system for determining anatomical tissue impedance characteristics for use in medical patient monitoring and treatment decision making, comprising: at least one repository configured to storing data indicating a plurality of predetermined expected impedance value ranges for a corresponding plurality of impedance measurements taken at a plurality of particular different sites of at least one anatomical organ; a substantially passive impedance measurement network operating exclusive of active current injection: an impedance measurement processor using said impedance measurement network and configured to automatically, receiving signal data representing a plurality of measured impedance values taken at a plurality of particular different sites of an anatomical organ and determining whether the received plurality of measured impedance values are within a corresponding plurality of predetermined expected impedance value ranges derived from data in said at least one repository and are correlated with an anatomical abnormality; and an output processor configured to automatically communicating data comprising at least one message to a destination, said at least one message includes data indicating whether said received plurality of measured impedance values are within said corresponding plurality of predetermined expected impedance value ranges and indicate said abnormality.
