Embodiment Construction

[0289] The accuracy of glucose sensors is important to patients, caregivers, and clinicians because estimated glucose concentration levels obtained from glucose sensors can be used to determine therapy or assess the effectiveness of therapy. There are many factors that can affect the accuracy of a glucose sensor. One factor is temperature. The inventors of the present invention have realized that, among other things, steps can be taken to compensate for the effect of temperature on the glucose sensor, which can improve the performance of the sensor system by increasing the accuracy of the estimated glucose level, which can reduce the sensor system's Mean Absolute Relative Deviation (MARD). The MARD value over a valid or indicative range of glucose levels is a common method used to describe the precision and accuracy with which a glucose sensing system makes glucose measurements. MARD is the result of a mathematical calculation that measures the average difference between the...

Abstract

This document discusses, among other things, systems and methods to compensate for the effects of temperature on sensors, such as analyte sensor. An example method may include determining a temperature-compensated glucose concentration level by receiving a temperature signal indicative of a temperature parameter of an external component, receiving a glucose signal indicative of an in vivo glucoseconcentration level, and determining a compensated glucose concentration level based on the glucose signal, the temperature signal, and a delay parameter.
