An apparatus for automatically reporting an event includes an actuator having a sensor for sensing the event and providing an actuation signal, a controller having a signal generator for formatting data corresponding to the event to form a report signal, and a transmitter for transmitting the report signal. The actuator may include a water-activated switch to sense the event or a motion detector to sense the event. The actuator may sense a signal corresponding to a change in a monitored physiological parameter of a person coupled to the apparatus. The apparatus may also include a global positioning system receiver. The report signal may be formed according to standard digital selective calling. A process of automatically reporting an event includes sensing the event, providing an actuation signal in response to the sensed event, formatting data corresponding to the event in response to the actuation signal, to form a report signal, and transmitting the report signal. Sensing the event may include sensing contact of a subject of the event with water, sensing an absence of motion of a subject of the event, or sensing a change in a monitored physiological parameter of a subject of the event. Data corresponding to the event may include global positioning system data. Formatting data corresponding to the event may include formatting the data according to standard digital selective calling protocol.
