ezCarb Examples with the Insulin on Board Feature Activated
If the Insulin on Board feature is activated, your Insulin on Board amount will be displayed for reference on
the ezCarb Bolus Total screen.
With the Insulin on Board feature activated, your suggested ezCarb total bolus amount will be as follows:
• If your current BG is above your target range, and your Insulin on Board amount is greater than your BG
correction amount, then your suggested total bolus amount will be your Carb Correction amount. This
is illustrated in example 1 that follows.
• If your current BG is within your target range, or equal to your target value, your suggested total bolus
amount will be your Carb correction.
• If your current BG is above your target range, and your BG correction amount is greater than your
Insulin on Board amount, then your suggested total bolus amount will be your Carb correction amount
plus your BG correction amount minus your Insulin on Board amount. This is illustrated in example 2
that follows.
• If your current BG is below your target range, your suggested total bolus amount will be your Carb
correction amount plus your BG correction amount minus your Insulin on Board amount. The
suggested total bolus amount will be 0.00U whenever the calculation results in a negative number.
A negative number implies that any additional insulin bolus amount would potentially result in over
delivery of insulin and hypoglycemia. Discuss the calculator feature with your HCP so you have a
thorough understanding of how it works before you begin using it.
The following examples illustrate typical screens you may encounter when using the ezCarb feature with
Insulin on Board activated. Insulin on Board amounts appear in the "IOB" field.

Example 1
2.26U
In Example 1, the Insulin on Board amount is displayed for reference but is
2.71U
not applied to the suggested total bolus amount. In this case, even though
3.00U
2.25U
your current BG level is above the target range, there is sufficient Insulin on
Board to cover the high BG. Therefore, the only insulin amount suggested is
to cover the carbs being consumed.
Example 2
2.26U
In Example 2, the Insulin on Board amount is displayed for reference and is
2.71U
applied to the suggested total bolus amount. In this case, your current BG is
1.00U
3.95U
above your target range, and your BG correction amount is greater than your
Insulin on Board amount. Therefore, the insulin amount suggested is to cover
the carbs being consumed, and any BG correction amount not already covered
by your Insulin on Board.
Example 3
2.26U
In Example 3, your current BG is below your target range, resulting in a negative
1.00U
0.50U BG correction amount. In this case, your carb amount needs to be offset by your
0.75U
BG correction amount since you are already below your target range. Therefore,
the insulin amount suggested is to cover only the carb amount not already
covered by your Insulin on Board amount and the negative BG correction
amount.
