18 Understanding SmartBolus Calculator Calculations
18.2. SmartBolus Calculator Examples
Example 1
Eating 50 g carbs, 0.6 U meal IOB and 0.5 U correction IOB from previous meal
and correction boluses. Sensor glucose is not available and a blood glucose
reading is not entered.
Correction Bolus
-- U
BG = N/A, Target Glucose = N/A
Correction Factor = N/A
Meal IOB adjustment
Meal IOB = 0.6 U
N/A: No BG reading
The SmartBolus Calculator
does not adjust your
correction bolus by the
meal IOB since there is no
glucose information.
Correction IOB adjustment
Correction IOB = 0.5 U
N/A: No BG reading
The SmartBolus Calculator
also does not adjust your
correction bolus by the
correction IOB since there is
no glucose information.
Meal Bolus
5 U
Carbs = 50 g, IC Ratio = 10 g/U
50 / 10 = 5 U
You are eating 50 g carbs.
With your IC ratio at 10, you
will need a 5 U meal bolus.
Correction IOB adjustment
IOB is subtracted from a bolus
only when BG is known.
Your meal bolus is not
adjusted by your IOB when
there is no blood glucose
reading or sensor glucose
value.
Calculated Bolus
5 U
The calculated bolus is just
the meal bolus since there
is no correction bolus.
Your Adjustment Meal bolus + 2 U 2 U
You can make manual
adjustments to your bolus
by tapping on the Total
Bolus eld at the bottom of
the SmartBolus Calculator
screen.
Total Bolus
=
7 U
The Total Bolus is the sum
of the calculated bolus
and any adjustments you
made.
