18 Understanding SmartBolus Calculator Calculations
Example 3
No carbs entered, used sensor glucose value of 10 mmol/L with a decreasing
trend. ere is 0.8 U of meal IOB and 0.5 U of correction IOB from the previous
meal and correction boluses.
Correction Bolus
0 U
Your glucose is 10 mmol/L, which
is 2.8 mmol/L over target. Because
your correction factor is 2.8, the
initial correction bolus is 1 U.
Sensor = 10,
Target Glucose = 7.2
Correction Factor = 2.8
(10 -7.2) / 2.8 = 1 U
Meal IOB adjustment
Meal IOB = 0.8 U
1 U - 0.8 U = 0.2 U
Since you have 0.8 U of meal IOB
remaining from a previous meal
bolus, this is subtracted from the
initial correction bolus of 1 U, and
you have 0.2 U of correction bolus
remaining.
You also have 0.5 U of correction IOB
from previous insulin action. This
is subtracted from the remaining
correction bolus of 0.2 U, driving
the nal calculated correction bolus
to 0 U. Note that 0.3 U of correction
IOB still remains after driving the
correction bolus to 0 U, and this is
used in the meal bolus calculations.
Correction IOB adjustment
Correction IOB = 0.5 U
0.2 U - 0.5 U ≤0 U
Meal Bolus
0 U
You did not enter any carbs, so you
do not receive any calculated meal
bolus dose.
Carbs = 0 g, IC Ratio = 10 g/U
0/10 = 0 U
Correction IOB adjustment
Remaining correction
IOB = 0.3 U
0 U - 0.3 U ≤ 0 U
Although there is a remaining
correction IOB of 0.3 U, your initial
meal bolus is already at 0 U, so it is
not adjusted further, and your meal
bolus remains at 0 U.
Calculated Bolus
0 U
Even though your glucose is above
target, you have enough IOB. As a
result, the SmartBolus Calculator
recommends that you do not
deliver any additional insulin.
Total Bolus
