8 Delivering a Bolus with the Bolus Calculator
8.1. About Delivering a Bolus
A bolus is a dose of insulin taken to correct an elevated blood glucose level (a
correction bolus) or to cover carbohydrates in a meal, drink, or snack (a meal
bolus).
About correction boluses and meal boluses
e Bolus Calculator calculates a suggested bolus amount of insulin to correct an
elevated blood glucose level (a correction bolus) and/or to cover carbohydrates
in a meal (a meal bolus). For additional details about how the Bolus Calculator
works, see page 256.

✓ Correction bolus
✓ Meal bolus
✓ ✓ Combined suggested
bolus
If you enter a blood glucose or CGM value that is above target but enter no carbs,
a correction bolus is calculated. If you enter carbs but not a blood glucose or CGM
value, a meal bolus is calculated. If you enter both a blood glucose or CGM value
and carbs, both factors are used to calculate a suggested bolus.
About using a CGM value with trend
Your CGM trend is based on the recent pattern of glucose changes. If you use
your CGM value, your CGM value and trend will be used to calculate a suggested
bolus amount. e CGM value and trend will be used along with your Correction
Factor to determine the correction portion of your bolus. e Bolus Calculator
will use the CGM trend to adjust the correction bolus amount.
When CGM Values are... e Bolus Calculator tries to keep

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.
