Abstract

Systems, methods and apparatus are provided for determining an estimate of an analyte level over time. The invention includes sampling sensor data using an analyte sensor positioned at least partially subcutaneously; storing a plurality of datasets of sensor data, each at a different rate; determining an estimated analyte level based on the datasets; and outputting the estimated analyte level to a display. Numerous additional aspects are disclosed.

Claims

1. A method comprising:

sampling sensor data using an analyte sensor;

storing a first dataset of the sensor data at a first rate;

storing a second dataset of the sensor data at a second rate;

determining an estimated analyte level based on the first and second datasets of the sensor data; and

outputting the estimated analyte level to a display.
