  • the definition titration glucose level is used to emphasize that this is not necessarily a fasting glucose value, rather the glucose titration level to base dose calculations on is low glucose values.
  • periods of low variance in glucose we use the information that the glucose is not influenced by short acting insulin, and we use periods of low average glucose within a specific time window. For example, we use a running average window of 3 hours and choose the window with the lowest value as the titration glucose level. This is useful in long acting insulin treatment since we are certain that there is no fast acting insulin causing the lowest values; all lowered glucose values are due to the long acting insulin or physiological changes.

  • the frequency of continuous glucose measurements can vary, and can span for example from a near continuous signal and up to 1 hour.
  • This method is similar to the running average in that it targets low glucose levels. Therefore it is relevant in basal insulin treatment. This method is more sensitive to low values and noise than the moving average, which might be beneficial in scenarios of e.g. patients with high hyporisk and high glucose variability. As previously mentioned examples of an embodiment can be seen in Figures 7A and 7B.

For each 24 hour long time interval, a window of 60 minutes, or 12 consecutive CGM measurements, runs through the glucose data and average of each window is calculated.

  • For the purpose of determining periods of fasting to be used as a titration glucose level we detect periods of low variance in glucose. We do this because glucose variance is typically higher during periods of external glucose entering the system than during fasting.
