17 Delivering a Bolus with the SmartBolus Calculator
If the current CGM value is below the dened Minimum Glucose for Calculations
setting, you will see a message that the SmartBolus Calculator is disabled. If the
CGM value displays "HIGH", the SmartBolus Calculator is temporarily disabled.
Note: If your Omnipod 5 System does not have a valid CGM value or trend at the
time you open the SmartBolus Calculator, the USE CGM option is disabled.
Tip: If you want to replace the CGM value with a blood glucose reading, tap the
CGM eld. See "Manually Enter Your Blood Glucose Reading" on page 242.
17.4. Insulin On Board (IOB)
Insulin on board, also known as IOB or active insulin, is the amount of insulin
that is still "active" in the body from a previous bolus or from automated insulin
delivery.
e SmartBolus Calculator considers the current IOB when calculating a
suggested bolus. Insulin on board may come from:
• Meal IOB - from previous meal boluses.
• Correction IOB - can be from previous correction boluses or from automated
insulin deliveries.
For more information, see "SmartBolus Calculator Rules" on page 264 and
"SmartBolus Calculator Equations" on page 263.
In certain circumstances you may decide to enter only carbs or the bolus amount
into the SmartBolus Calculator. is may be desired if you want to only bolus for
carbs using your programmed insulin to carbohydrate ratio, or you want to deliver
an amount of insulin based on your own estimate. If entering only carbs or a bolus
amount without a glucose value, IOB is not subtracted from your suggested bolus
dose as the calculator is not able to adjust the bolus dose if your glucose value is
not known. If you want IOB to be considered, enter a glucose value. Here is an
example to demonstrate when you may choose to enter only the carb or bolus
amount into the SmartBolus Calculator.
Example: You are about to have lunch and you are unsure of how much you will
eat. To avoid taking too much insulin, you deliver a meal and correction bolus
based on the carbs you know you will eat and your glucose value. Aer delivering
the bolus and eating the rst portion, you decide you want to nish the remaining
portion. Since you already delivered a correction with the previous bolus, and you
know glucose values are on the rise, you decide to deliver a second bolus for only
the remaining carbs in your meal and not enter another glucose value.
