Optimizing pump therapy
Square Wave and Dual Wave boluses
Square Wave bolus delivers a bolus evenly over a period of time (30 minutes to 8-hours). This bolus
can be used for insulin delivery when you have eaten a long meal with extended snacking. It can also be
useful if you have delayed food digestion due to gastroparesis or meals high in fat. A Square Wave bolus
can be useful if a normal bolus drops your blood glucose too quickly. Since the Square Wave portion
extends over a period of time, the insulin is more likely to be available to match your individual needs.
NOTE -
During delivery of a Square Wave bolus, you will not be able to do the following pump
functions: change the max bolus amount, disable or deliver dual and Square Wave boluses, do a
fixed prime or rewind, change the active insulin time, run a self-test, or access the User Settings
menu. All other pump functions are still available during the Square Wave bolus.
Dual Wave bolus delivers a combination of an immediate normal bolus followed by a Square Wave
bolus. The Square Wave portion is delivered evenly over a period of time. A Dual Wave bolus is useful
for meals with both rapidly and slowly absorbed carbohydrates. For example, a Dual Wave bolus would
be appropriate for fruit and crackers followed by pasta. The Dual Wave option meets both immediate
and extended insulin needs. A Dual Wave bolus is also useful for correcting elevated blood glucose
before a meal.
