Abstract
A method for creating alarm signals based on time-series signal behavior determined from real-time discrete data obtained from a medical device. In one embodiment the method includes identifying patterns in preceding time-series measurement threshold breaches in clinical readings obtained from said medical device when associated with a particular patient, and initiating an alarm signal to a front-line clinician based on the preceding quantity of threshold breaches.
Claims8
A method for creating alarm signals based on time-series signal behavior of real-time discrete clinical data obtained from a medical device continuously monitoring a patient, the method comprising:
- setting upper and lower thresholds in the patient's real-time discrete clinical data;
- identifying breaches of upper and lower thresholds in the patient's real-time discrete clinical data;
- calculating a moving average over a defined time interval in the real-time discrete clinical data;
- setting new upper and lower thresholds within the defined time interval in response to the moving average;
- determining each new breach of the new upper and lower thresholds in subsequent defined time intervals;
- and
- calculating subsequent changes in the upper and lower thresholds if the number of breaches of the upper and lower thresholds exceeds a predetermined amount.
