Abstract

Embodiments of the present invention provide methods, apparatuses, and systems associated with detecting, monitoring, analyzing, and/or displaying analyte level trends in a body. In an embodiment, there is provided a method comprising obtaining a plurality of analyte measurements from a body using an analyte sensing device, and selecting two or more measurements of the plurality of measurements to calculate and display on a device associated with the analyte sensing device a rate of change of the analyte over a period of time spanning the two or more measurements.

Claims

1. A method, comprising:

measuring with an analyte sensing device a plurality of analyte values of an individual for a plurality of points of time over a defined time period;

determining for the plurality of points of time over the defined time period a rate of change of the plurality of analyte values; and

displaying a graphical representation of the rate of change, wherein said determined rate of change is represented as a best fit rate of change from among a plurality of predefined options indicative of relative rates of change, and wherein the best fit rate of change is highlighted.

2. The method of claim 1, wherein said defined time period has a duration of less than 10 minutes.

3. The method of claim 1, wherein said defined time period has a duration of 5 minutes to 30 minutes.

4. The method of claim 1, wherein said graphical representation is displayed on an electronic monitoring unit.

5. The method of claim 1, wherein said graphical representation is displayed on a personal computer.

6. The method of claim 1, wherein said graphical representation depicts a plurality of predefined options indicative of relative rates of change.

7. The method of claim 1, further comprising a secondary notification indicating a current or future condition based on the determined rate of change.

8. The method of claim 7, wherein said secondary notification is displayed as a textual description of the current or future condition.

9. The method of claim 7, wherein said secondary notification comprises an audible alert or alarm.

10. The method of claim 1, further comprising determining the best fit rate of change in accordance with a selection rule incorporating one or more factors to select one rate of change as the best fit of change as opposed to another rate of change.

11. The method of claim 1, wherein highlighting the best fit rate of change comprises highlighting more than one rate of change when the determined rate of change is not an exact match to a single predefined best fit rate of change.

12. A method, comprising:

obtaining a plurality of analyte measurements from a body using an analyte sensing device; and

selecting two or more measurements of the plurality of measurements to calculate and display on a device associated with the analyte sensing device a rate of change of the analyte over a period of time spanning the two or more measurements.

13. The method of claim 12, wherein the displayed rate of change is a representation of the calculated rate of change.

14. The method of claim 12, wherein the displayed rate of change is a best fit representation of the calculated rate of change.

15. The method of claim 12, wherein the rate of change is displayed on the device graphically.

16. The method of claim 12, wherein the rate of change is displayed on the device textually.

17. The method of claim 12, further comprising a secondary notification indicating a current or future condition based on the determined rate of change.

18. The method of claim 17, wherein said secondary notification is displayed as a textual description of the current or future condition.

19. The method of claim 17, wherein said secondary notification comprises an audible alert or alarm.

20. An apparatus, comprising:

an analyte sensing device coupled to an electronic monitoring unit, said electronic monitoring unit comprising a storage medium and a plurality of programming instructions stored in the storage medium adapted to program an apparatus to enable the apparatus to;

measure with an analyte sensing device a plurality of analyte values of an individual for a plurality of points of time over a defined time period;

determine for the plurality of points of time over the defined time period a rate of change of the plurality of analyte values; and

display a graphical representation of the rate of change, wherein said determined rate of change is matched to a best fit rate of change among a plurality of predefined options indicative of relative rates of change, and wherein the best fit rate of change is highlighted.
