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: 40 mg/dL (2.2 mmol/L) per unit of insulin
➠BG Target: 90-120 mg/dL (5.0 - 6.7 mmol/L)
➠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 “Bolus Wizard feature
specifications” on page 150.
Example 1: Blood glucose within target range 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 Paradigm Link meter and his blood glucose reading of
120 mg/dl (6.7 mmol/L) 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) 60g
15g/u = 4 units (correction) Correction is 0 because the current blood
glucose reading is within his BG Target Range
= 4 + 0
= 4 units
estimate = 4 units
