Systems and methods for providing sensitive and specific alarms
First Claim
1. A method of activating a hypoglycemic indicator based on continuous glucose sensor data, the method comprising:
- evaluating sensor data using a first function to determine whether a real time glucose value meets one or more user settable first criteria;
evaluating sensor data using a second function to determine whether a predicted glucose value meets one or more non user settable second criteria;
activating a hypoglycemic indicator if either the one or more user settable first criteria or the one or more non user settable second criteria are met; and
providing an output based on the activated hypoglycemic indicator.

Abstract
Systems and methods for providing sensitive and specific alarms indicative of glycemic condition are provided herein. In an embodiment, a method of processing sensor data by a continuous analyte sensor includes: evaluating sensor data using a first function to determine whether a real time glucose value meets a first threshold; evaluating sensor data using a second function to determine whether a predicted glucose value meets a second threshold; activating a hypoglycemic indicator if either the first threshold is met or if the second threshold is predicted to be met; and providing an output based on the activated hypoglycemic indicator.

23. A method of activating a hypoglycemic indicator based on continuous glucose sensor data, the method comprising:
-
evaluating sensor data using a first function to determine whether a real time glucose value meets one or more user settable first criteria; evaluating sensor data using a second function to determine whether a predicted glucose value meets one or more non user settable second criteria, wherein the second function utilizes a first order autoregressive model to determine the predicted glucose value, wherein the first order autoregressive model comprises a forgetting factor, a prediction horizon and a prediction threshold tuned to provide no more than one additional alarm per week based on a retrospective analysis comparing the use of the first function and the second function together as compared to the first function alone; activating a hypoglycemic indicator if either the one or more user settable first criteria or the one or more non user settable second criteria are met; and providing an output based on the activated hypoglycemic indicator.
