Example 2: Not eating, BG of 8.4 mmol/L is above target, 1 U meal IOB,
1 U correction IOB
Duration of Insulin Action = 4 hours.
Three hours ago, you delivered an 8 U bolus (4 U meal bolus, 4 U correction
bolus) because you were eating and had a high blood glucose reading.
Now, three hours after the 8 U bolus, there are 2 U of IOB left (1 U meal IOB, 1 U
correction IOB).
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 = 1 U
1 U - 1 U = 0 U
Correction IOB adjustment
Correction IOB = 1 U
N/A: Correction bolus is <= 0 U
Meal bolus
Carbs = 0 g, IC Ratio = 15 g/U
0 / 15 = 0 U
Correction IOB adjustment
Remaining correction IOB = 1 U
0 U - 1 U = 0 U
Calculated bolus
Your adjustment
Total Bolus
0 U
Your blood glucose is 2.8
mmol/L over your target. A
correction factor of 2.8 gives a 1 U
preliminary correction bolus.
However, this preliminary
correction bolus is reduced
to zero by the 1 U meal IOB
adjustment.
Because the preliminary
correction bolus has been
reduced to zero, the correction
IOB is not subtracted.
0 U
You are not eating, so your meal
bolus is 0 U.
None of the correction IOB was
subtracted from the correction
bolus, so the remaining
correction IOB is 1 U. However,
the meal bolus is already zero.
0 U
Although your blood glucose
is above target, the meal IOB
reduces the total bolus to 0 U.
