Example 3
Current BG level: 100 mg/dL
Carb intake: 45 carbs
Meal IOB: 1 unit
Correction insulin on board (IOB): 0 units
Carb intake: 45 carbs
Meal IOB: 1 unit
Correction insulin on board (IOB): 0 units
Correction bolus: 100 mg/dL (current) – 100 mg/dL (target) = 0
0 ÷ 50 (CF) = 0 units
Meal bolus: 45 (carbs) ÷ 15 (IC ratio) = 3 units
Suggested bolus dose = 0 (correction) + 3 (meal) – 0 (IOB) = 3U
Example 4
Current BG level: 150 mg/dL
Carb intake: 60 carbs
Meal insulin on board (IOB): 0 units
Correction IOB: 1 unit
Carb intake: 60 carbs
Meal insulin on board (IOB): 0 units
Correction IOB: 1 unit
Correction bolus: 150 mg/dL (current) – 100 mg/dL (target) = 50
50÷ 50 (CF) = 1 unit
Meal bolus: 60 (carbs) ÷ 15 (IC ratio) = 4 units
Suggested bolus dose = 1 (correction) + 4 (meal) – 1 (IOB) = 4U
Calculator guidelines
When the suggested bolus calculator is turned On, the OmniPod
System applies these guidelines to the suggested bolus doses:
System applies these guidelines to the suggested bolus doses:
•
Suggested bolus doses are rounded down to the nearest
0.05U.
0.05U.
•
If the total of the suggested bolus calculation (correction
bolus plus meal bolus) is less than zero, the suggested bolus
dose is 0.00U.
bolus plus meal bolus) is less than zero, the suggested bolus
dose is 0.00U.
•
The System will not suggest a bolus dose if your current
blood glucose (BG) reading is below the minimum BG you
have set for bolus calculation (see Chapter 2, Getting Started,
and Chapter 6, Using the Personal Diabetes Manager).
blood glucose (BG) reading is below the minimum BG you
have set for bolus calculation (see Chapter 2, Getting Started,
and Chapter 6, Using the Personal Diabetes Manager).
•
The System suggests a correction bolus only when your BG
reading is above the correction threshold or correct-above
value you have set (see Chapter 2, Getting Started, and
Chapter 6, Using the Personal Diabetes Manager).

•
Meal IOB, which is insulin on board from a previous meal
bolus, is subtracted first from the current correction bolus, if
any, until it is zero. However, any remaining meal IOB is never
subtracted from the current meal bolus.

any, until it is zero. However, any remaining meal IOB is never
subtracted from the current meal bolus.
•
Correction IOB, which is insulin on board (active insulin) from
a previous correction bolus, is then subtracted from the cur-
rent correction bolus, if any remains, until it is zero. At that
point, any remaining correction IOB is subtracted from the
current meal bolus.
a previous correction bolus, is then subtracted from the cur-
rent correction bolus, if any remains, until it is zero. At that
point, any remaining correction IOB is subtracted from the
current meal bolus.
Meal IOB is never subtracted from another meal
bolus—only from a correction bolus.
