■
Active insulin only reduces the correction portion of the estimate, not the food portion.
■
If the active insulin is more than the correction estimate, the correction portion of the estimate will be changed to zero (0).
■
If the current BG is lower than target, the correction portion of the estimate will reduce the total estimate.
■
If a Dual Wave bolus is less than the estimate due to the max bolus limit or user change, the square (sq) portion is reduced first.
Bolus Wizard examples: (settings:) Carb ratio: 30 grams/unit
Insulin
sensitivity: 40 mg/dL/unit
Target BG: 120 mg/dL
#1: No previous bolus activity for at least 10 hours. User inputs 60 grams of carbs and does not enter BG.
#2: No previous bolus activity for at least 10 hours. User inputs 60 grams of carbs and a BG of 200.
#3: No previous bolus activity for at least 10 hours. User inputs 60 grams of carbs and a BG of 80.
