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 to be at 70 mg/dL (3.9 mmol/L), which is below his Low BG Target of 90 mg/dL (5.0 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.
(food estimate)
60 g
15 g/u
= 4 units
- 0* units (active insulin) = 0.5 units+
(correction estimate)
= 4 + (-0.5)
= 3.5 units
bolus estimate
3.9 mmol/L - 5.0 mmol/L
2.2 mmol/L/u
- 0* units (active insulin) = 0.5 units
70 mg/dL - 90 mg/dL
40 mg/dL/u
NOTE: *When the current blood glucose is below the target low blood glucose, the active insulin amount
is not considered in the Bolus Wizard feature calculations.
