Getting hold of doctors in an emergency has for years been done through pagers. With the ubiquity of wireless networks in hospitals, Vocera communications has come up with thier Vocera Communication System. It's akin to the communicator in Star Trek, featuring voice commands to talk to specific people, groups of people, or to locate and talk to the nearest doctor. This allows for instant 2 way communication. A big jump over pagers.
