Target BG
When calculating a correction bolus, the Bolus Calculator aims to bring your
blood glucose down to the Target BG.
Correct Above threshold
e Bolus Calculator only suggests a correction bolus if your blood glucose
reading is above your Correct Above setting. is feature can prevent corrections
to blood glucose values that are only slightly higher than your Target BG.
Insulin on board
Insulin on board (IOB) is the amount of insulin still active in your body from
earlier boluses. IOB from previous correction boluses is referred to as correction
IOB. IOB from previous meal boluses is referred to as meal IOB.
When calculating a new bolus, the Bolus Calculator may reduce the suggested
bolus based on the IOB.
e Duration of Insulin Action setting represents the amount of time that insulin
remains “on board” or “active” in your body.
Note: e Bolus Calculator only subtracts IOB from a suggested bolus if your
current blood glucose is known. You should always test your blood glucose prior
to delivering a bolus.
Duration of Insulin Action
e Bolus Calculator uses your Duration of Insulin Action setting to calculate the
insulin on board from prior boluses.
Minimum BG for Calcs
e Bolus Calculator does not suggest a bolus if your blood glucose reading is
below your Minimum BG for Calcs level.
Reverse Correction
If the Reverse Correction setting is turned on and your blood glucose level
is below your Target BG, the Bolus Calculator uses the calculated negative
correction bolus to reduce the meal bolus. is allows part of the meal to be used
to raise the low blood glucose level towards the Target BG.
If the Reverse Correction setting is turned o, the Bolus Calculator suggests the
full meal bolus even if your blood glucose level is below your Target BG.
