Abstract
Systems and methods for dynamically and intelligently estimating analyte data from a continuous analyte sensor, including receiving a data stream, selecting one of a plurality of algorithms, and employing the selected algorithm to estimate analyte values. Additional data processing includes evaluating the selected estimative algorithms, analyzing a variation of the estimated analyte values based on statistical, clinical, or physiological parameters, comparing the estimated analyte values with corresponding measure analyte values, and providing output to a user. Estimation can be used to compensate for time lag, match sensor data with corresponding reference data, warn of upcoming clinical risk, replace erroneous sensor data signals, and provide more timely analyte information encourage proactive behavior and preempt clinical risk.

21. A system for monitoring a glucose concentration of a host using a continuous glucose sensor, the system comprising:
-
a continuous glucose sensor configured to measure a glucose concentration of a host; a sensor electronics unit configured to electrically couple to the continuous glucose sensor, generate glucose sensor data indicative of a host'"'"'s measured glucose concentration using the continuous glucose sensor, and transmit the glucose sensor data; and a receiver device configured to receive the transmitted glucose sensor data and process the glucose sensor data, the receiver device comprising a graphical user interface, wherein the receiver device is configured to display on the graphical user interface a gradient bar divided into a plurality of zones, each of the plurality of zones representing a different level of risk to the host, and wherein the receiver device is additionally configured to display on the graphical user interface a marker that indicates a zone of the plurality of zones within which the host'"'"'s measured glucose value falls. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
