Walk past a patient's hospital room, and the flashing control panels on devices by the bed might make you think you're peering at the cockpit of a 737.
Medical technology can make patient care better and more precise. But the gadgets and computers can cause trouble, too. One big problem is that most of the devices can't communicate with one another.
The ultimate technological goal is what the engineers call interoperability. Let the ventilators, IV pumps, heart monitors and computers holding patient records communicate and update one another automatically.
