Problems solved by technology
For example, the patient risk associated with 100 mg / dl and rapidly falling blood glucose levels is likely to be greater than the patient risk associated with 100 mg / dl with a constant rate of glucose change
Additionally, the measured glucose results from the glucose sensor may contain sensor noise, such as noise due to physical movement of the glucose sensor relative to the person's body or due to electrical noise inherent in the glucose sensor
Additionally, the glucose sensor may malfunction, such as due to electronics or battery failure or due to detachment or loss of the sensor
As such, the measured glucose level may not be accurate
Penalty values provided by the Kovatchev function fail to account for such uncertainties in the measured glucose levels

Embodiment Construction
[0029] For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will however be understood that no limitation of the scope of the present disclosure is thereby intended.
[0030] The term "logic" or "control logic" as used herein may include software and / or firmware implemented on one or more programmable processors, application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), Digital Signal Processor (DSP), hardwired logic, or a combination thereof. Thus, depending on the embodiment, various logic may be implemented in any suitable manner and will continue to be consistent with the embodiments disclosed herein.
[0031] As used herein, a "measured glucose value" or "measured glucose result" is a person's glucose level as measured by a glucose sensor; an "actual glucose level" is a person'...

A system and method is provided for analyzing a glucose state. A method may include identifying a target glucose state and an initial glucose state. The method may include calculating a target return path for a transition from the initial glucose state to the target glucose state. The target return path may comprise at least one intermediate glucose state associated with the transition from the initial glucose state to the target glucose state. The target return path may be calculated based on a hazard associated with the at least one intermediate glucose state of the target return path.
Description
technical field [0001] The present disclosure relates generally to continuous glucose monitoring (CGM) and in particular to systems and methods for assessing risk associated with glucose status. Background technique [0002] Biological monitoring provides healthcare providers (HCPs) and patients with biological data that can be used to treat and / or manage medical conditions involving biological data. For example, continuous glucose monitoring (CGM) devices provide glucose data relating to the detected level or concentration of glucose contained within the blood of people with diabetes (PwDs). A risk metric can be derived from the glucose data for use in assessing the risk to a person with diabetes based on the detected glucose levels. However, current risk metrics typically fail to account for the rate of change of glucose data and the uncertainty in the accuracy of glucose data. As such, current risk metrics are generally not suitable as a metric for optimizing treatment ...
