Claim 7:
8. A method of monitoring glucose in a patient, the method comprising the steps of:
receiving from a continuous glucose monitoring (CGM) device a series of glucose values associated with the patient, wherein the series of glucose values are generated by the CGM device performing periodic glucose measurements for the patient;
determining a signal to noise ratio (SNR) associated with the periodic glucose measurements;
upon determining that the SNR is at a first SNR level, evaluating, using a first algorithm, a differential change in glucose value over time (dg/dt) based on the series of glucose values;
upon determining that the SNR is at a second SNR level, evaluating, using a second algorithm, the differential change in glucose value over time (dg/dt) based on the series of glucose values, wherein the first SNR level is lower than the second SNR level;
generating a smoothed glucose value that is indicative of the series of glucose values;
estimating a dynamic risk based on the smoothed glucose value and dg/dt;
comparing the dynamic risk to a predetermined threshold; and
generating a display representative of the smoothed glucose value and generating a perceptible alarm when the dynamic risk is greater than the predetermined threshold.
