Bolus Wizard feature examples
For the scenarios that follow, Michael has his Bolus Wizard feature turned on with the following settings:
Carb ratio: 15 grams per unit of insulin
Insulin Sensitivity: 2.2 mmol/L (40 mg/dL) per unit of insulin
BG Target: 5.0–6.6 mmol/L (90–120 mg/dL)
Active Insulin Time: 6 hours
NOTE: If you want to see details of the formulas the Bolus Wizard feature uses to calculate estimate
boluses like the ones in the following examples, see the Bolus Wizard feature specifications section in the
Pump specifications chapter.
Example 1: Blood glucose on target (normal blood glucose) and no active insulin
Michael awakens in the morning before school and his mother has breakfast waiting for him. Before he
begins eating, he tests his blood glucose with his meter and his blood glucose result of 6.6 mmol/L
(120 mg/dL) is automatically sent to his pump.
He estimates that his meal consists of 60 grams of carbohydrates. When prompted by the Bolus Wizard
feature, he enters this amount in the ENTER FOOD screen. Based on his Bolus Wizard feature settings, the
pump will suggest that he take 4.0 units of insulin.
Food estimate:
Bolus estimate = Food estimate + Correction estimate
Bolus estimate = 4 units + 0 = 4 units
60 g
15 g/u
= 4 units
Correction estimate:
Correction is 0 because the current blood glucose reading
is within the BG Target range.
