A processor implemented monitoring system includes a sensor coupled to the processor for sampling a physiological parameter of a subject which may comprise a subject unique identification parameter. Also coupled to the processor is a physical location determining device. Subject location as well as parameter status data are input to the processor which is programmed to determine whether the parameter and/or location data falls within prescribed boundaries stored in a memory. Upon determination of an out of boundary condition, e.g. subject entered proscribed geographic area, monitored medical parameter, e.g. blood pressure, out of limit or an unauthorized person attempting to operate a vehicle, etc., the processor transmits information pertaining to the subject, the off limit condition and the specific geographic location of the subject to a central monitoring station for implementation of appropriate action.
