Abstract
Abstract A system and method for identifying and displaying medical data items which violate programmable alarm conditions are provided. The system of the present invention automatically alerts the medical practitioner if changes or deviations in parametric and physiologic medical data items violate programmable alarm conditions. The system also provides the medical practitioner with the ability to edit, disable, and enable programmable alarm conditions associated with one or more parametric and physiologic medical data items. The system also allows the medical practitioner to select a range of medical data to be used when the determination of whether any alarm conditions were violated is made.
