SIGNAL PROCESSING FOR CONTINUOUS ANALYTE SENSOR
First Claim
1. A method for estimating an analyte value from a continuous analyte sensor, the method comprising:
- receiving a data stream from the continuous analyte sensor for a first time period;
estimating at least one analyte value for a second time period based at least in part on the data stream for the first time period; and
analyzing a variation of the at least one estimated analyte value.

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.
