Example 1: Dual Wave bolus
Set a Dual Wave bolus for a barbecue style dinner
Carol is going to a barbecue at a friend's house. Her meal consists of:
mixed green salad fruit salad a dinner roll and margarine
potato salad baked beans pork ribs with barbecue sauce.
She calculates her total carbohydrates and determines her total meal bolus amount. She knows that
she will need some insulin immediately for the fruit, barbecue sauce and dinner roll and some insulin
spread out over time for the high fat and high fiber content of the rest of the meal. Carol will
program her pump to deliver a Dual Wave bolus with ½ of the total bolus to be given immediately
and the other half over a 2- hour* duration.
(* This particular duration of time and bolus proportions is an example. As always, you should consult
with your healthcare professional for your individual needs.)
