Medical devices don't communicate with each other

As technology moves forward, people expect the electronic devices of everyday life to work together, from cell phones that can call or text-message other phones, to computers that interconnect with a slew of gadgets. But in the medical world, where the stakes are higher, such flexible interconnection is rare. Each device operates in its own silo. Now the push for greater connectedness in hospital electronics is gaining momentum. The goal is devices that can not only plug into one another, but can also "understand" each other and automatically identify potential life-threatening problems sooner than they would have been caught by busy nurses and doctors.
