Food estimate:
Carb grams ÷ Carb ratio = Units of insulin
Correction estimate:
(Current BG - High BG Target) ÷ Insulin sensitivity - Active insulin = Units of
insulin
Total bolus estimate:
Food estimate + Correction estimate = Units of insulin
2. If your current BG is less than your Low BG Target, the Bolus Wizard feature
adds the BG correction estimate to the food estimate to get the total bolus
estimate.
