Bolus Calculator examples
For an explanation of IOB, see page 147. For an explanation of the correction and
meal bolus equations, see page 149.
Example 1: Eating 45 g carbs, BG of 8.4 mmol/L is above target, no IOB
Duration of Insulin Action = 4 hours. You have not delivered a bolus in the last
4 hours, so there is no IOB (no meal IOB, no correction IOB).
Correction Bolus
1 U
Your blood glucose is 2.8
mmol/L over your target. With
your correction factor at 2.8 and
no IOB adjustment, you will need
a 1 U correction bolus.
BG = 8.4, Target BG = 5.6
Correction Factor = 2.8
(8.4-5.6) /2.8 = 1 U
Meal IOB adjustment
Meal IOB = 0 U
1 U - 0 U = 1 U
No IOB, so no IOB adjustment.
Correction IOB adjustment
Correction IOB = 0 U
1 U - 0 U = 1 U
No IOB, so no IOB adjustment.
Meal Bolus
3 U
You are eating 45 g carbs. With
your IC ratio at 15 and no IOB
adjustment, you will need a 3 U
meal bolus.
Carbs = 45 g, IC Ratio = 15 g/U
45 / 15 = 3 U
Correction IOB adjustment
Remaining correction IOB = 0 U
3 U - 0 U = 3 U
No IOB, so no IOB adjustment.
Calculated Bolus
4 U
The calculated bolus is the sum
of your correction bolus and
meal bolus.
Your Adjustment
0 U
Any adjustment you make to the
calculated bolus is shown here.
No adjustment was made.
Total Bolus
4 U
The total bolus is the sum of
the calculated bolus and any
adjustment made by you.
