17.1. About the SmartBolus Calculator
A bolus is a dose of insulin taken to cover carbohydrates in a meal, drink or snack
(a meal bolus) or to correct elevated glucose (a correction bolus). e SmartBolus
Calculator calculates a suggested bolus amount of insulin to bring down high
glucose (a correction bolus) and/or to cover carbohydrates in a meal (a meal
bolus).
About Correction Boluses and Meal Boluses
If you enter a blood glucose reading or sensor glucose value that is above target,
but enter no carbs, a correction bolus is calculated. If you enter carbs, but not a
blood glucose reading or sensor glucose value, a meal bolus is calculated. If you
enter both a blood glucose reading or sensor glucose value and carbs, both factors
are used to calculate a suggested bolus.

About Using a Sensor Glucose Value with Trend
Your sensor glucose trend is based on the recent pattern of glucose changes. If you
use your sensor glucose value, your sensor glucose value and trend will be used
to calculate a suggested bolus amount. e sensor glucose value and trend will be
used along with your Correction Factor to determine the correction portion of
your bolus. e SmartBolus Calculator will use the sensor glucose trend to adjust
the correction bolus amount.

Trending up (increasing) Adds more insulin to the correction
bolus.
Trending down (decreasing) Subtracts insulin from the correction
bolus.
Steady No adjustment to the correction
bolus.
