Embodiment Construction

[0012] Various embodiments of the present invention provide a method and system for managing alarm events in a physiological monitoring system, particularly in a centralized patient monitoring system.

[0013] figure 1 A physiological monitoring system 100 is shown in accordance with an exemplary embodiment of the present invention; the physiological monitoring system 100 includes one or more monitoring stations 102, a processor 104, an alarm level modification module 106, and a display panel 108. One or more monitoring stations 102 monitor one or more events associated with one or more physiological signals associated with one or more patients in the hospital and may be wired (referred to as "bedside physiology monitor") or wireless. The one or more alarm events reflect the physiological condition of the one or more patients. Monitoring station 102 may, for example, monitor one or more of electrocardiogram (ECG), non-invasive blood pressure (NBP), and specific blood oxygen ...

Abstract

The invention relates to a method for managing alarm events in a physiological monitoring system. The method includes validating the accuracy of alarm events by checking if the alarm events are noise events. The method further includes identifying a pattern in alarm sequence or an alarm rate of at least one alarm type associated with the alarm events. The alarm rate is the frequency of the occurrence of alarm events for the particular alarm type. Based on the identified pattern in the alarm sequence and the alarm rate and patient data, an alarm level associated with the alarm type is adjusted. The hospital staff is notified depending on the criticality of the adjusted alarm level. Further, the alarm signals are suppressed when either a patient intervention or a pause signal is detected by the physiological monitoring system.

Description

technical field [0001] The present invention relates generally to physiological monitoring systems, and more particularly to managing alarms generated in physiological monitoring systems. Background technique [0002] Physiological monitoring systems generally include multiple monitoring stations to monitor alarm signals associated with multiple patients. Alarm levels are assigned to alarm signals to indicate the current physiological condition of the patient. Based on this alarm level, the physiological monitoring system provides important information related to the patient's condition to the hospital staff. Therefore, hospital staff provide appropriate services to patients (known as patient intervention). A typical physiological monitoring system notifies hospital staff based on the alarm level associated with the detected pattern in the monitoring waveform of the alarm signal. However, inappropriate alarm signals may be generated in physiological monitoring systems whe...
