METHOD FOR MANAGING ALARMS IN A PHYSIOLOGICAL MONITORING SYSTEM
First Claim
1. A method for managing one or more alarm events in a physiological monitoring system, the method comprising:
- validating the one or more alarm events associated with one or more alarm signals;
identifying a pattern in the sequence of the one or more alarm events associated with at least one alarm type, the at least one alarm type being associated with the one or more alarm signals;
adjusting an alarm level associated with the at least one alarm type based on the identified pattern in the sequence of the one or more alarm events and patient data;
responding to the one or more alarm events based on the alarm level; and
suppressing the one or more alarm events based on one or more pre-defined conditions, wherein suppressing the one or more alarm events comprises automatically resetting the alarm level.

Abstract
A method for managing alarm events in a physiological monitoring system is described. 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.

7. A physiological monitoring system comprising:
-
one or more monitoring stations configured to monitor one or more alarm events associated with one or more alarm signals, the one or more alarm signals being associated with one or more patients; and a processor comprising an alarm level adaptation module configured to; identify a pattern in sequence of detected alarm events associated with at least one alarm type by tracking an alarm rate associated with the alarm type for a pre-defined time interval, the at least one alarm type being associated with the one or more alarm signals; set an alarm rate limit associated with the at least one alarm type based on population-average data and pattern in the alarm rate for a patient; adjust the alarm level associated with the at least one alarm type based on the identified pattern in the sequence of the alarm events, the alarm rate and patient data; and suppress the one or more alarm events via automatic resetting of the alarm level based on one or more pre-defined conditions. - View Dependent Claims (8, 9, 11, 12, 13, 14, 15, 16, 17, 18, 19)
