Optimizing pump therapy
Square Wave and Dual Wave bolus
Square Wave bolus delivers a bolus evenly over a specified 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 BG too rapidly. Since the Square Wave portion extends over a period of time, the insulin is more
likely to be available to match your individual needs.
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.
