A system for actively monitoring a patient, said system comprising: at least one body-worn monitoring device, each said at least one body-worn monitoring device including at least one sensor that continuously measures at least one physiologic parameter and that is capable of detecting at least one predetermined physiologic event based on measured data from said at least one sensor; at least one intermediary device linked to said at least one body-worn monitoring device by a first wireless network, wherein said at least one patient-worn monitoring device is programmed to transmit a beacon for maintaining periodic connectivity over said first wireless network with said at least one intermediary device; and at least one respondent device linked to said at least one intermediary device through at least one second wireless network, said at least one of said body-worn monitoring device, said at least one intermediary device and said at least one respondent device being programmed to perform a specified function automatically when said predetermined physiologic event is realized, said first wireless network is a low-power local wireless network in an "off" state with the exception of said periodic beacon until the detection of said predetermined physiologic event; and said first wireless network is placed in an "on" state at the detection of said predetermined physiologic event by said at least one body-worn monitoring device, said "on" state automatically causing said at least one body-worn monitoring device to transmit continuously measured physiologic parameter data to said at least one intermediary device, said at least one body-worn monitoring device having a unique patient identifier, said unique patient identifier being appended to each data packet transmitted over said periodic beacon when said first wireless network is in the "off" state and with said continuously measured physiologic parameter data to said at least one intermediary device when said network is in said "on" state, said second network being a medium to long range wireless network which is predominantly in an "off" state, characterized in that said intermediary device having a processor with logic for analyzing said physiologic parameter data received from said body-worn monitoring device to verify the occurrence of said physiologic event and to place said at least one second wireless network in an "on" state and to transmit data over said at least one second wireless network to said at least one respondent device if the occurrence of said physiologic event is verified. at least one body-worn monitoring device, each said at least one body-worn monitoring device including at least one sensor that continuously measures at least one physiologic parameter and that is capable of detecting at least one predetermined physiologic event based on measured data from said at least one sensor;
