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-
out the day and night (see Chapter 3, Understanding and
Adjusting Basal Rates).
The size of a
bolus dose
depends on the factors current at the
time you deliver the bolus:
•
Your
blood glucose level
•
Your
insulin-to-carbohydrate ratio
•
Your
correction factor
•
Your target blood glucose
•
The amount of
insulin on board (active insulin
)
•
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 OmniPod System, it is easy to adapt to any situation.
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 you adjust
these settings.
