Abstract
Embodiments of the present disclosure include detecting a concurrent occurrence of a decrease in monitored analyte level and a corresponding decrease in monitored on-skin temperature, confirming a presence of an impending hypoglycemic condition, and asserting a notification corresponding to the confirmed impending hypoglycemic condition. Devices, methods, systems and kits incorporating the same are also provided.
Claims16
A system, comprising:
- an analyte sensor positioned in fluid contact with interstitial fluid under a skin layer and configured to generate signals corresponding to a monitored analyte level in the interstitial fluid;
- sensor electronics electrically coupled to the analyte sensor and configured to generate analyte data based on the signals generated by the analyte sensor;
- and
- a data receiver configured to receive the generated analyte data from the sensor electronics, the data receiver configured to trigger a hold assertion function to temporarily prevent the assertion of a programmed notification after the programmed notification has initiated when a rate of change of the monitored analyte level determined from the generated analyte data exceeds a predetermined analyte threshold during a monitoring time period, and to assert the programmed notification when the rate of change of a monitored temperature exceeds a predetermined temperature threshold during the monitoring time period.

A system, comprising
- sensor electronics configured to receive signals from an analyte sensor in fluid contact with interstitial fluid, and to generate analyte data corresponding to a monitored analyte level in interstitial fluid;
- and
- a data receiver configured to receive the generated analyte data from the sensor electronics, the data receiver configured to temporarily prevent the assertion of a programmed notification after the programmed notification has initiated when a rate of change of the monitored analyte level determined from the generated analyte data exceeds a predetermined analyte threshold during a monitoring time period, but to assert the programmed notification when a rate of change of a monitored temperature exceeds a predetermined temperature threshold during the monitoring time period.
