Abstract

A medication safety device and method can include an infusion pump and a drug library in communication with the infusion pump. The drug library can have upper hard and soft limits and lower hard and soft limits associated with at least one drug. A graphical user interface can display a bar chart showing upper and lower soft limit bars for the at least one drug. The upper and lower soft limit bars can be grabbed and dragged on the graphical user interface in touch-screen fashion to new positions associated with new upper and lower soft limits. The graphical user interface and associated hardware and software can be configurable to responsively re-analyze data and compare a particular infusion to the new upper and lower soft limits.
