Signal processing for continuous analyte sensor
First Claim
1. A method for estimating sensor data from a continuous analyte sensor, comprising:
- receiving sensor data from a continuous analyte sensor for a first time period;
processing the sensor data, using an electronic system, to obtain a plurality of estimated analyte values at a future point in time based at least in part on an extrapolation of the sensor data for the first time period and an analysis of a variation of the extrapolated sensor data; and
providing output, wherein providing output comprises displaying, on a display of the electronic system, an indication of the plurality of estimated analyte values.

Abstract
A second numerical value 246 is shown, which is representative of a variation of the measured analyte value 242. The second numerical value is preferably determined from a variation analysis based on statistical, clinical, or physiological parameters, such as described in more detail elsewhere herein. In one embodiment, the second numerical value 246 is determined based on clinical risk (for example, weighted for the greatest possible clinical risk to a patient). In another embodiment, the second numerical representation 246 is an estimated analyte value extrapolated to compensate for a time lag, such as described in more detail elsewhere herein. In some alternative embodiments, the receiver displays a range of numerical analyte values that best represents the host'"'"'s estimated analyte value (for example, +/−10%). In some embodiments, the range is weighted based on clinical risk to the patient. In some embodiments, the range is representative of a confidence in the estimated analyte value and/or a variation of those values. In some embodiments, the range is adjustable.
