First Claim
Patent Images
1. A method, comprising:
- acquiring a physiological parameter value and a first alarm setting defining a first alarm condition;
identifying a sensitivity associated with the first alarm setting;
selecting a second alarm setting based on the identified sensitivity associated with the first alarm setting, the second alarm setting defining a second alarm condition;
determining in parallel whether the physiological parameter value meets the first alarm condition or the second alarm condition;
generating a first alarm instruction upon a determination that the physiological parameter value meets the first alarm condition;
generating a second alarm instruction upon a determination that the physiological parameter value meets the second alarm condition; and
triggering an alarm in response to the generation of the first alarm instruction or the generation of the second alarm instruction.

Abstract
A technique for managing alarms includes acquiring a physiological parameter value and one or more alarm settings associated with the physiological parameter value. The technique also includes determining if the one or more alarm settings are associated with an adaptive alarm manager selecting an adaptive alarm condition from a plurality of adaptive alarm conditions when the one or more alarm settings are associated with the adaptive alarm manager; determining if the physiological parameter value meets the selected adaptive alarm condition; and generating an alarm in response when the physiological parameter value meets the selected adaptive alarm condition.

16. A method, comprising:
-
receiving a physiologic parameter, and a first alarm setting defining a first alarm condition; determining that the first alarm setting is associated with a first alarm sensitivity; identifying a second alarm setting defining a second alarm condition, the second alarm setting being associated with a second alarm sensitivity that is lower than the first alarm sensitivity; adjusting the second alarm setting such that the second alarm sensitivity becomes higher than the first alarm sensitivity; determining in parallel whether the physiologic parameter meets the first alarm condition or the second alarm condition; generating a second alarm instruction upon a determination that the physiologic parameter meets the second alarm condition but not the first alarm condition; and triggering an alarm in response to the second alarm instruction.

17. A method, comprising:
-
processing a photoplethysmograph (PPG) signal to calculate a physiologic parameter; comparing the physiologic parameter to a first alarm setting to identify a first alarm condition, wherein the first alarm setting is associated with a first alarm sensitivity; comparing the physiologic parameter to a second alarm setting to identify a second alarm condition, wherein a second alarm sensitivity associated with the second alarm setting is based on the first alarm sensitivity, and wherein the second alarm sensitivity is higher than the first alarm sensitivity; determining in parallel the physiologic parameter meets the second alarm condition but not the first alarm condition; and triggering an alarm associated with the second alarm setting in response to determining the physiologic parameter meets the second alarm condition but not the first alarm condition.
