Example 2: Dual Wave bolus -
Set a Dual Wave bolus for correcting elevated blood glucose before a meal
Marsha uses the Square Wave bolus for the majority of her meals. She tests her pre-meal blood
glucose and finds that it is above her target level. Marsha would like to correct her elevated blood
glucose before she eats. The Dual Wave bolus can be used to deliver some insulin now to help
correct her blood glucose elevation, and then deliver her Square Wave bolus to cover her meal.
