Example 2
Eating 30 g carbs, no meal or correction IOB. Used CGM value of 180 mg/dL,
with a rising trend.
Correction Bolus
1.2 U
Your glucose is
180 mg/dL which is 50 mg/
dL over your target. Because
your correction factor is 50, the
initial correction bolus is 1 U.
CGM = 180, Target Glucose = 130
Correction Factor = 50
(180-130) / 50 = 1 U
Meal IOB adjustment
Meal IOB = 0 U
1 U – 0 U = 1 U
The SmartBolus Calculator
does not adjust your
correction bolus by the meal
IOB since there is no meal IOB.
Correction IOB adjustment
Correction IOB = 0 U
1 U - 0 U = 1 U
Adjusted correction bolus = 1.2 U
Adjusted for CGM: Rising
The SmartBolus Calculator
also does not adjust your
correction bolus by the
correction IOB since there is no
correction IOB.
The correction bolus is
increased to account for your
rising CGM trend.
Meal Bolus
3.6 U
You are eating 30 g carbs. With
your IC ratio at 10, you will
need a 3 U meal bolus.
The SmartBolus Calculator
does not adjust your meal
bolus by the correction IOB
since there is no correction
IOB.
Carbs = 30 g, IC Ratio = 10 g/U
30 / 10 = 3 U
Correction IOB adjustment
Remaining correction IOB = 0 U
3 U – 0 U = 3 U
Adjusted meal bolus = 3.6 U
Adjusted for CGM: Rising
The SmartBolus Calculator
does not adjust your meal
bolus by the correction IOB
since there is no correction IOB.
The meal bolus is increased to
account for your rising CGM
trend.
Calculated Bolus
4.8 U
The calculated bolus is the
sum of your correction bolus
and meal bolus that has been
adjusted for rising CGM value.
Total Bolus
4.8 U
The total bolus is the sum of
the calculated bolus and any
adjustment you made.
