Example 5: Blood glucose below target (low blood glucose) with active insulin
Another day at school, Michael is getting ready to eat lunch. He tests his blood glucose with his meter and
finds it at 3.9 mmol/L (70 mg/dL), which is below his Low BG Target of 5.0 mmol/L (90 mg/dL). 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.
Food estimate:
Bolus estimate = Food estimate + Correction estimate
Bolus estimate = 4 units + (-0.5) units = 3.5 units
60 g
15 g/u
= 4 units
= -0.5 units
Correction estimate:
3.9 mmol/L - 5.0 mmol/L
2.2 mmol/L/u
= -0.5 units
70 mg/dL - 90 mg/dL

*When the current blood glucose is below the Low BG Target, an active insulin
amount is not considered in the Bolus Wizard feature calculations.
