Setting What it does
Carb Ratio
Exchange Ratio
Used for food bolus calculations.
• If you count carbs: the number of carb grams that are
covered by 1 unit of insulin.
• If you count exchanges: the number of insulin units that
are needed to cover 1 carb exchange.
Insulin Sensitivity
Factor
Used to calculate correction bolus amounts.
Your insulin sensitivity factor is the amount that blood
glucose is reduced by one unit of insulin.
BG Target The Bolus Wizard calculates your estimated bolus based
on your BG target range. The high and low values you set
are the values to which your blood glucose is corrected.
To use a single target value rather than a range, set the
same value for High and Low.
If your BG value is above the high target value, a
correction dose is calculated. If your BG value is below
the low target value, a negative correction is calculated
and subtracted from your food bolus.
Active Insulin Time Active insulin is the bolus insulin that has been delivered
by the pump and is still working to lower your blood
glucose levels. Active insulin time is the length of time
that bolus insulin is tracked as active insulin.
Work with your healthcare professional to get the active
insulin time that best represents the insulin type you use
and your physiological insulin absorption rate.
For more information about how the Bolus Wizard uses
your active insulin amount, see About active insulin, on
page 72.
