Automatic adaptive limit and level management of arrhythmia alarms

Automatic adaptive alarm limit and level management logic, to reduce workflow for electrocardiographic monitoring devices, is described. Performance and functional requirements for alarm limit and level adaptation logic are developed. The design for a single patient processing unit of adaptive alarm management logic for a single alarm, a collection of concurrent and asynchronous Timed Input/Output Automata, is presented. Performance results are provided on a data set consisting of 158 alarm records, roughly approximating a month´s admissions in an Intensive Care Unit at a large hospital.
