Appendix B: Bolus Advice Calculations
The Mathematical Basis for Bolus Calculations
The following is a list of the most important formulas and the calculation principles on which bolus advice is
based. It is difficult to accurately calculate a bolus yourself using these formulas when the acting time and
offset time of recent meals and correction boluses are considered.
Carbohydrate Suggestion
This calculation is made when the blood glucose test result falls below the hypo warning limit. It is based
on the other values defined for the current time block and the result is calculated as a carbohydrate intake
recommendation.

• A minimum amount of 12g (or equivalent BE, KE, or CC units) is always given. If the calculated value
is below 12g, then 12g is used.
• The carbohydrate suggestion is displayed in the carb unit of measure you have selected (g, BE, KE, or
CC).
