Tracking the health status of a patient includes entering a plurality ofhealth record signals (201). Each signal comprises a record of measurement ofa predetermined health indicative parameter considered to be in a normal rangerelated to the health status of the patient taken at different times (202).The health record signals are stored in memory (30). The stored health recordsignals are processed (14) to project a possible trend for the predeterminedhealth parameter (203) to assume a value in the abnormal range. A futurabnormal indication signal is provided when the trend forecasts thepredetermined parameter will assume a value in the abnormal range (204).
