A wireless relay module comprising: an electrical connector configured to receive primary power from a power source; a battery configured to provide secondary power upon a changed characteristic of primary power; a first receiver capable of wirelessly receiving medical device data over a wireless relay network formed of wireless relay modules (30,30a), the data from at least one medical device; a first transmitter capable of wirelessly transmitting medical device data over the wireless relay network of wireless relay modules (30,30a); a second transmitter capable of wirelessly transmitting data over an internet accessible wireless communications network; and a processor coupled to the first and second transmitters (31,32), said processor configured to control said wireless relay module to select one of said first and second transmitter (31,32) for transmitting the medical device data received by said first receiver; and said processor further configured to produce a power alarm signal upon a changed characteristic of the primary power, determine whether at least a second wireless relay module (30,30a) communicating on the same wireless relay network is accessible to receive a message or if at least the second wireless relay module (30,30a) is inaccessible repeat a search for a further relay module (30,30a) that is accessible, and send the power alarm signal to at least the second wireless relay module (30,30a) or the further relay module (30,30a) for proliferation of the power alarm signal over the wireless relay network if it is determined that the second wireless relay module (30,30a) or the further relay module (30,30a) is accessible. an electrical connector configured to receive primary power from a power source; a battery configured to provide secondary power upon a changed characteristic of primary power; a first receiver capable of wirelessly receiving medical device data over a wireless relay network formed of wireless relay modules (30,30a), the data from at least one medical device; a first transmitter capable of wirelessly transmitting medical device data over the wireless relay network of wireless relay modules (30,30a); a second transmitter capable of wirelessly transmitting data over an internet accessible wireless communications network; and a processor coupled to the first and second transmitters (31,32), said processor configured to control said wireless relay module to select one of said first and second transmitter (31,32) for transmitting the medical device data received by said first receiver; and said processor further configured to produce a power alarm signal upon a changed characteristic of the primary power, determine whether at least a second wireless relay module (30,30a) communicating on the same wireless relay network is accessible to receive a message or if at least the second wireless relay module (30,30a) is inaccessible repeat a search for a further relay module (30,30a) that is accessible, and send the power alarm signal to at least the second wireless relay module (30,30a) or the further relay module (30,30a) for proliferation of the power alarm signal over the wireless relay network if it is determined that the second wireless relay module (30,30a) or the further relay module (30,30a) is accessible.
