Example 3
Current BG level: 5.6 mmol/L
Carb intake: 45 carbs
Meal IOB: 1 unit
Correction (IOB): 0 units
Correction bolus: 5.6 mmol/L (current) – 5.6 mmol/L (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: 8.4 mmol/L
Carb intake: 60 carbs
Meal (IOB): 0 units
Correction (IOB:) 1 unit
Correction bolus: 8.4 mmol/L (current) – 5.6 mmol/L (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 mylife
OmniPod System applies these guidelines to the suggested
bolus doses:
•
Suggested bolus doses are rounded down to the nearest
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.
•
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).
•
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.
Meal (IOB) is never subtracted from another meal
bolus—only from a correction bolus.
