Abstract
Generally, methods, devices, and systems for generating a hybrid analyte level output are provided. The uncompensated analyte levels lag in time with respect to the lag-compensated analyte levels, and the hybrid analyte level output tracks between the uncompensated analyte levels and the lag-compensated analyte levels according to predetermined criteria.

37. A method of generating a hybrid analyte level output, comprising:
-
receiving sensor data comprising uncompensated analyte levels received from an in vivo sensor, wherein the uncompensated analyte levels comprise interstitial fluid glucose levels; deriving lag-compensated analyte levels from the uncompensated analyte levels, wherein the lag-compensated analyte levels comprises estimated blood glucose levels; and generating a hybrid analyte level output comprised of the uncompensated analyte levels and the lag-compensated analyte levels, wherein the uncompensated analyte levels lag in time with respect to the lag-compensated analyte levels; wherein the hybrid analyte level output tracks between the uncompensated analyte levels and the lag-compensated analyte levels according to a predetermined criteria, wherein the predetermined criteria comprises; criteria for tracking the uncompensated analyte levels when selected analyte levels are below a predetermined threshold and have been rising for at least a predetermined duration of time; and criteria for tracking the lag-compensated levels when the selected analyte levels are at or above the predetermined threshold or have been constant for at least the predetermined duration of time. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45)
