SYSTEM AND METHOD OF DISCOVERING, DETECTING AND CLASSIFYING ALARM PATTERNS FOR ELECTROPHYSIOLOGICAL MONITORING SYSTEMS
First Claim
1. An electrophysiological monitoring system comprising:
- a plurality of sensors configured to detect one or more health parameters of a patient;
a monitoring device configured to receive a plurality of sensing signals from the sensors and output a monitoring signal representative of an alarm sequence, wherein the alarm sequence comprises a set of alarm events identified in the sensing signals; and
an on-line monitoring module configured to;
generate a suffix tree data structure in response to the monitoring signal to identify alarm patterns from the set of alarm events;
classify the alarm sequence in response to the occurrences of alarm patterns in the alarm sequence; and
alert monitoring personnel of an alarm condition after processing the alarm sequence in real-time.

Abstract
A system and method for electrophysiological monitoring system including a plurality of sensors configured to detect one or more health parameters of a patient and a monitoring device configured to receive a plurality of sensing signals from the sensors and output a monitoring signal representative of an alarm sequence, wherein the alarm sequence comprises a set of alarm events identified in the sensing signals. The system also includes an on-line monitoring module configured to generate a suffix tree data structure in response to the monitoring signal to identify alarm patterns from the set of alarm events and classify the alarm sequence in response to the occurrences of alarm patterns in the alarm sequence. The on-line monitoring module is further configured to alert monitoring personnel of an alarm condition after processing the alarm sequence in real-time.

6. A method for electrophysiological monitoring comprising steps of:
-
receiving a monitoring signal derived from a patient wherein the monitoring signal provides an alarm sequence; developing a suffix substring data structure to identify a plurality of alarm patterns from the alarm sequence; generating an incidence vector that determines a relative incidence of each type of alarm pattern with respect to the plurality of alarm patterns in the alarm sequence; grouping the incidence vector in a cluster using a clustering algorithm; classifying one or more patients according to their pattern incident rates which are obtained by extraction of (possibly concurrent) alarm patterns and storing the classification of the incidence vector in a database. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method for electrophysiological monitoring that detects and classifies alarm patterns comprising steps of:
-
receiving a monitoring signal from a patient wherein the monitoring signal provides an alarm sequence, wherein the alarm sequence includes at least one alarm pattern; developing a suffix substring data structure in real-time to identify alarm patterns of medical interest contained in the alarm sequence; generating an incidence vector in response to the suffix substring data structure; classifying the alarm sequence to a classification cluster using a classification algorithm based on the incidence vector; and alerting monitoring personnel to indicate a condition corresponding to the cluster after processing the alarm sequence in real-time. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
