A combination bolus (part of the dose now, the rest delivered over time) is called Multiwave on Accu-Chek, Combo on Animas, and Dual Wave on Medtronics.
An extended bolus (all the dose delivered evenly over a specified period) is called Extended on the Accu-Chek and Animas, and Square Wave on Medtronic.
Both options are available on the Omnipod under “Extended.”
That’s as of spring 2016.
The trick, of course, is judging how much the protein and fat will raise you later, and when, and how much of your dose you should therefore extend.
