Abstract

A wireless medical monitoring system and medical monitoring devices adapted to communicate using a plurality of wireless protocols and networks. For each transmission of data, a wireless protocol or network is selected based on the properties of the available protocols and networks and the nature of the data that is to be transmitted. Thus, the medical system and devices can move seamlessly from one context and location to another. The medical devices may also include additional features, such as detection of improperly positioned or disconnected sensors and auditory and/or visual prompting of the patient to correct the problem. In some embodiments, the medical monitoring devices may comprise body area networks of individual sensors communicating and cooperating with one another wirelessly.
