1. A method, comprising:
- receiving a physiological signal or a physiological parameter value;
generating an alarm in response to a determination that the physiological signal or physiological parameter value meets an alarm condition;
receiving a relevance indicator indicating a relevance of the generated alarm;
storing the relevance indicator and the alarm condition;
repeating the steps of receiving the physiological signal, generating the alarm, receiving the relevance indicator, and storing the relevance indicator to store a plurality of relevance indicators and a plurality of corresponding alarm conditions;
analyzing the plurality of relevance indicators and the plurality of corresponding alarm conditions; and
modifying at least one alarm condition of the plurality of corresponding alarm conditions based on the analyzing.

Abstract
A method for storing data relating to generated alarms includes receiving a physiological signal or a physiological parameter value. The method also includes generating an alarm in response to a determination that the physiological signal or physiological parameter value meets an alarm condition. Additionally, the method includes receiving a relevance indicator indicating a relevance of the generated alarm and storing the relevance indicator and the alarm condition.
