Example 3: Eating 45 g carbs, BG of 5.6 mmol/L is at target, 1 U meal IOB
Duration of Insulin Action = 4 hours.
Three hours ago, you delivered a 4 U bolus (4 U meal bolus) because you were
eating. There was no correction bolus because your blood glucose was at your
Target BG.
Now, three hours later and just before your next meal, there is 1 U of IOB from the
previous meal, which is a 1 U meal IOB. There is no correction IOB because the
earlier bolus had no correction component.
Correction Bolus
BG = 5.6, Target BG = 5.6
Correction Factor = 2.8
(5.6-5.6) / 2.8 = 0 U
Meal IOB adjustment
Meal IOB = 1 U
N/A: Correction bolus is <= 0 U
Correction IOB adjustment
Correction IOB = 0 U
N/A: Correction bolus is <= 0 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
Calculated Bolus
Your Adjustment
Total Bolus
0 U
Blood glucose is at target, so the
correction bolus is zero.
The correction bolus is zero, so
the meal IOB is not subtracted.
No IOB adjustment.
3 U
You are eating 45 g carbs.
With your IC ratio at 15 and no
correction IOB adjustment, the
meal bolus is 3 U.
No IOB adjustment is made.
There is no correction IOB, and
meal IOB is never subtracted
from a meal bolus.
3 U
Even though there was a 1 U
meal IOB, it did not reduce the
calculated bolus.
