*Note: When the current BG is below the target low BG, an active insulin amount that is greater than the correction estimate is not
considered in the Bolus Wizard feature calculations.
Example 5: BG below target (low BG) with active insulin
Another day at school, Michael is getting ready to eat lunch. He tests his BG with his linked meter and
finds it at 70 mg/dL (3.9 mmol/L), which is below his Low BG target of 90 mg/dL (4.9 mmol/L). His
reading is automatically sent to his pump.
When prompted by the Bolus Wizard feature, he enters his carbohydrate amount of 60 grams in the
ENTER FOOD screen. Based on his settings, and despite 1.5 units of active insulin, his pump will suggest
that he take 3.5 units of insulin.
