Abstract

Method and apparatus for determining and outputting projected alarms or notifications associated with anticipated hyperglycemic or hypoglycemic conditions are provided. Systems and kits employing the devices described herein executing the one or more routines described are also provided.

Claims

1. An analyte monitoring system, comprising:

an analyte sensor in operative contact with an analyte, the sensor adapted to generate a plurality of data points associated with a monitored analyte concentration;

a processor adapted to process the plurality of data points generated by the analyte sensor; and

logic implemented by the processor to determine whether a current data point of the plurality of data points is within a predetermined threshold zone, wherein if it is determined that the current data point is within the predetermined threshold zone, the logic implemented by the processor determines a rate of change of the analyte level based on the received plurality of data points, to determine if the rate of change indicates the projected glucose value exceeding the alarm threshold within a predetermined amount of time, and to perform one or more of a line fit analysis of a slope or anticipated alarm condition persistence evaluation when the determined rate of change indicates that the projected glucose level exceeds the alarm threshold within the predetermined amount of time.
