    摘要： Methods and apparatus for analyte level estimation are provided for filtering measurement data. In an embodiment, a present predicted analyte level estimate is determined. A present corrected analyte level estimate is determined based at least in part on the determined present predicted analyte level estimate and a received present monitored analyte measurement data. One or more of the medication infusion rate or the received present monitored analyte measurement data are filtered using a rate variance filter, wherein when the medication infusion rate exceeds a predetermined threshold level, the rate variance filter is adjusted from a predetermined setting to a modified setting to be responsive to changes in the present monitored analyte measurement data after a predetermined time period lapses.

    摘要： Analyte sensor faults are detected. Datasets of glucose values sensor electronics are coupled to a glucose sensor in fluid contact with interstitial fluid under a skin surface. Baseline median glucose value and glucose variability values are computed, based on the first dataset. A baseline data point is stored. Evaluation median glucose value and variability are computed, based on the second dataset of glucose values. An evaluation data point is stored. A magnitude of a vector that extends between the baseline data point and the evaluation data point is computed. A component of the magnitude of the vector that is parallel to a hypoglycemia risk contour line is computed and compared to a predefined threshold value. An indication that a sensor fault has been detected if the component is greater than a threshold is displayed.
