Abstract

A medical fluid delivery system (300) includes workflow construction logic (304) to create one or more workflows (307) from a plurality of available workflow components (306). The created workflows (307) may each contain a proper subset of workflow components from the plurality of available workflow components (306). The workflows (307) may be created using the workflow construction logic (304) and a user interface (302) by selecting and arranging graphical elements representing workflow components (306). The constructed workflows (307) may correspond with the practices of a given care group. The medical fluid delivery system (300) may further include workflow execution logic (305) operable to execute the workflows (307). When executed, the workflows (307) may sequentially guide a user through each of the included workflow components (306) using a fled interface. The nomenclature displayed by the workflow components (306) during workflow execution may be customizable.
