Bolus Wizard feature examples

Settings:

• Carb ratio: 30 grams/unit

• BG Target: 90–120 mg/dL (5.0–6.7 mmol/L)

• Insulin Sensitivity: 40 mg/dL/unit (2.2 mmol/L/unit)

•Active Insulin Time: 6 Hours

1 No active insulin from previous bolus delivery. User inputs 60 grams of carbs and does not enter BG.

Food estimate:

Carb grams ÷ Carb ratio = Units of insulin

60 g ÷ 30 g/u = 2 units

Total bolus estimate = Food estimate = 2 units

2 No active insulin from previous bolus delivery. User inputs 60 grams of carbs and a BG of 200 mg/dL

(11.1 mmol/L).

Food estimate:

Carb grams ÷ Carb ratio = Units of insulin

60 g ÷ 30 g/u = 2 units

Correction estimate:

(Current BG - High BG Target) ÷ Insulin sensitivity = Units of insulin

(200 mg/dL - 120 mg/dL) ÷ 40 mg/dL/u = 2 units, or

(11.1 mmol/L - 6.7 mmol/L) ÷ 2.2 mmol/L/u = 2 units

Total bolus estimate:

Food estimate + Correction estimate = Units of insulin

2 units + 2 units = 4 units

3 No active insulin from previous bolus delivery. User inputs 60 grams of carbs and a BG of 70 mg/dL

(3.9 mmol/L).

Food estimate:

Carb grams ÷ Carb ratio = Units of insulin

60 g ÷ 30 g/u = 2 units

Correction estimate:

(Current BG - Low BG Target) ÷ Insulin sensitivity = Units of insulin

(70 mg/dL - 90 mg/dL) ÷ 40 mg/dL/u = -0.5 units, or

(3.9 mmol/L - 5.0 mmol/L) ÷ 2.2 mmol/L/u = -0.5 units

Total bolus estimate:

Food estimate + Correction estimate = Units of insulin

2 units + (-0.5) units = 1.5 units
