Abstract
Methods and systems for detecting false alarms. Methods and systems described herein may receive data associated with an alarm signal using an interface, extract at least one artifact feature from the received data, and then receive a classification of the alarm signal as a true positive or false positive based on the at least one extracted artifact feature. The classifier may be configured to execute an ensemble of decision trees.
Claims18
A method for detecting false alarms, the method comprising:
- receiving from a patient monitoring device, using an interface, patient data associated with an alarm signal issued by the patient monitoring device;
- extracting, using a feature extraction module, at least one artifact feature from the received patient data;
- providing, using a classifier, a classification of the alarm signal as a true positive or false positive based on the at least one extracted artifact feature;
- and
- assigning a score to the at least one artifact feature indicating a contribution of the at least one artifact feature to the false alarm upon classifying the alarm signal as a false positive.
A system for detecting false alarms, the system comprising:
- an interface configured to receive from a patient monitoring device patient data associated with an alarm signal issued by the patient monitoring device;
- a memory;
- a processor executing instructions stored on the memory to provide:
- a feature extraction module configured to extract at least one artifact feature from the received patient data,
- a classifier configured to provide a classification of the alarm signal as a true positive or false positive based on the at least one extracted artifact feature, and
- a scoring module configured to assign a score to the at least one artifact feature indicating a contribution of the at least one artifact feature to the false alarm upon classifying the alarm signal as a false positive.
A non-transitory computer readable medium containing computer-executable instructions for detecting false alarms, the medium comprising:
- computer-executable instructions for receiving from a patient monitoring device, using an interface, patient data associated with an alarm signal;
- computer-executable instructions for extracting, using a feature extraction module, at least one artifact feature from the received patient data;
- computer-executable instructions for providing, using a classifier, a classification of the alarm signal as a true positive or false positive based on the at least one extracted artifact feature;
- and
- computer-readable instructions for assigning a score to the at least one artifact feature indicating a contribution of the at least one artifact feature to the false alarm upon classifying the alarm signal as a false positive.
