CHAPTER 4
Understanding and Delivering Bolus Doses
What Is a Bolus?
A bolus is an extra dose of insulin, delivered when needed to: 
Match the carbohydrates (sugar content) in a meal or snack—
also known as a meal bolus
Lower blood glucose when it gets too high—also known as a 
correction bolus
This extra dose is in addition to the basal rate delivered through-
The size of a bolus dose depends on the current factors at the 
time you deliver the bolus:
Your blood glucose level
Your insulin-to-carbohydrate ratio
Your correction factor
Your target blood glucose and correct above threshold
The amount of insulin on board (IOB) (active insulin) from pre-
vious meal and correction boluses
Your correction threshold, the BG level above which you 
would like to take insulin to reduce an elevated blood 
glucose 
Your activity level
The type and amount of food you eat
With the mylife OmniPod System, it is easy to adapt to any situa-
tion. With just a few button presses, you can adjust to 
unexpected or changing insulin needs.
During setup, you entered bolus dose settings in the PDM (see 
Chapter 2, Getting Started). You can adjust these settings as you 
fine-tune your System or when your needs change (see Chapter 
6, Using the Personal Diabetes Manager).
Check with your healthcare provider before adjust-
ing these settings.
