False alarm reduction systems and related methods

A method for determining the relevancy of a plurality of alarms, the method comprising:

• gathering physiological data using a plurality of sensors, wherein the plurality of sensors is configured to be coupled to a patient;
• determining a physiological state of the patient using the physiological data, using a medical monitoring device coupled to the plurality of sensors through a telecommunication channel;
• using the medical monitoring device, issuing a plurality of alarm states;
• evaluating the plurality of alarm states using a processing unit, the processing unit configured to use a coalition-based feature selection method;
• determining the relevancy of each alarm state of the plurality of alarm states using the processing unit;
• and
• issuing one or more alarms corresponding with each relevant alarm state to a computing device associated with a user;
• wherein the coalition-based feature selection method includes a Banzhaf power and classifies a one or more chosen top informative alarms from the plurality of top informative alarms into false alarms and true alarms using a Bayes-Net classifier using the processing unit;
• and
• wherein choosing the plurality of top informative alarms comprises determining a most informative subset of alarm states from among the plurality of alarm states, wherein determining further comprises establishing a relevance of the subset of alarm states to a target user and determining an interdependence among the subset of alarm states.

A method for issuing an alarm regarding a physiological state of a patient, the method comprising:

• receiving a plurality of alarm states from a medical monitoring device at a processing unit through a telecommunication channel;
• choosing a plurality of top informative alarms using a Banzhaf power and the processing unit;
• classifying a one or more chosen top informative alarms from the plurality of top informative alarms into false alarms and true alarms using a Bayes-Net classifier using the processing unit;
• and
• issuing at least one alarm to a computing device associated with a user if any one or more chosen top informative alarms is classified as true;
• wherein choosing the plurality of top informative alarms further comprises determining a most informative subset of alarm states from among the plurality of alarm states, wherein determining further comprises establishing a relevance of the subset of alarm states to a target user and determining an interdependence among the subset of alarm states.
