A medical monitoring system comprising:

• a plurality of portable electronics units each sized to be carried by a person being monitored and each comprising:
• an electronic controller;
• at least one memory coupled to the electronic controller that at least temporarily stores (a) sensor data provided by at least one sensor associated with the monitored person in response to at least one physiological characteristic of the monitored person, and (b) statistical data processed from or related to sensor data provided by the at least one sensor;
• a communications unit coupled to the electronic controller that transmits sensor data over a wireless communications link and receives over the wireless link statistical data based from or related to sensor data transmitted by the communications unit, the statistical data received by the communications unit being stored at least temporarily in the at least one memory;
• and
• a display device that displays at least statistical data stored in the at least one memory;
• and
• a remote computer and associated memory that at least temporarily stores sensor data and statistical data processed from or related to the stored sensor data, the communications unit of the electronics unit transmitting sensor data for receipt by the computer and receiving statistical data provided by the computer;
• the display displaying statistical data provided only by the remote computer.
