4 No active insulin from previous bolus delivery. User inputs 60 grams of carbs and a BG of 100 mg/dL
(5.6 mmol/L).
Food estimate:
Carb grams ÷ Carb ratio = Units of insulin
60 g ÷ 30 g/u = 2 units
Correction estimate:
Correction is 0 because the current BG reading is within the BG Target range.
Total bolus estimate:
Food estimate + Correction estimate = Units of insulin
2 units + 0 units = 2 units
5 Previous bolus activity results in a calculation of 1.5 units unabsorbed (active) insulin. 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 - Active insulin = Units of insulin
(200 mg/dL - 120 mg/dL) ÷ 40 mg/dL/u - 1.5 units = 0.5 units, or
(11.1 mmol/L - 6.7 mmol/L) ÷ 2.2 mmol/L/u - 1.5 units = 0.5 units
Total bolus estimate:
Food estimate + Correction estimate = Units of insulin
2 units + 0.5 units = 2.5 units
6 Previous bolus activity results in a calculation of 3.5 units unabsorbed (active) insulin. 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 - Active insulin = Units of insulin
(200 mg/dL - 120 mg/dL) ÷ 40 mg/dL/u - 3.5 units = -1.5 units*, or
(11.1 mmol/L - 6.7 mmol/L) ÷ 2.2 mmol/L/u - 3.5 units = -1.5 units*
NOTE: *This negative number indicates that active insulin is sufficient to cover the correction that is
needed. Thus, correction is 0 units. Active insulin does not reduce the food portion of the estimate.
Total bolus estimate:
Food estimate + Correction estimate = Units of insulin
2 units + 0 units = 2 units
