Methods and Apparatuses for Providing Adverse Condition Notification in Analyte Monitoring Systems
First Claim
1. A method for concurrently supporting multiple data communication modes including data communication in response to a request and autonomous data communication based on monitored parameter detection, comprising:
- receiving time spaced glucose signals from an in vivo glucose sensor in fluid contact with interstitial fluid;
buffering the received time spaced glucose signals in a memory;
detecting a request for real time glucose level information, wherein when the request for real time glucose level information is detected, transmitting the buffered glucose signals and real time glucose signal received from the glucose sensor to a remotely located device;
processing a subset of the received time spaced glucose signals to identify a predetermined number of consecutive glucose data points from the subset of the received time spaced glucose signals indicating an impending adverse condition;
confirming the impending adverse condition based on comparison of the predetermined number of consecutive glucose data points to a stored glucose data profile associated with the impending adverse condition, wherein confirming the impending adverse condition includes generating a notification signal when the impending adverse condition is confirmed; and
activating a radio frequency (RF) communication module to wirelessly transmit the generated notification signal to the remotely located device only when the notification signal is generated.

Abstract
Methods, devices, systems, and kits are provided that buffer the time spaced glucose signals in a memory, and when a request for real time glucose level information is detected, transmit the buffered glucose signals and real time monitored glucose level information to a remotely located device, process a subset of the received glucose signals to identify a predetermined number of consecutive glucose data points indicating an adverse condition such as an impending hypoglycemic condition, confirm the adverse condition based on comparison of the predetermined number of consecutive glucose data points to a stored glucose data profile associated with the adverse condition, where confirming the adverse condition includes generating a notification signal when the impending hypoglycemic condition is confirmed, and activate a radio frequency (RF) communication module to wirelessly transmit the generated notification signal to the remotely located device only when the notification signal is generated.
