Fatal mix-ups too commonly result from the complexity of managing the multiple simultaneous intravenous drug infusions of hospital patients. Manual tracing of each IV tube is time-consuming and error-prone, and as such it is easy for a nurse to deliver an incorrect dosage by programming the pump for the wrong medication. The CareFusion team is designing a system that will help the nurse verify which IV bag is attached to each pump, thereby reducing the incidence of incorrect pairings.
