* Insulin sensitivity should equal the amount (in mg/dL or mmol/L) that blood glucose will be lowered after taking 1 unit of insulin.
To determine insulin sensitivity, divide 1500 by Total Daily Dose (TDD**) of Insulin. The answer is your “Correction Factor”
(1500 Rule). As always, consult with your healthcare professional for guidance.
**TDD = Total amount of basal and bolus insulin delivered in a 24-hour day.
Example #3:
Meal bolus, correction bolus and insulin sensitivity
3a.
Jason is ready to eat his breakfast. He has calculated that he will need 4.0 units for his food.
He tests his blood glucose and finds that it is 200 mg/dl (11 mmol/L). Jason knows that his blood glucose level is
above his pre-meal blood glucose target and will need additional insulin before he eats.
Jason's healthcare professional has determined the following for him:
pre-meal target BG: 110 mg/dL (6.1 mmol/L)
*Insulin sensitivity: 30 mg/dL (1.7 mmol/L)
3b.
Jason determines that he will need a correction bolus of 3.0 units insulin to lower his elevated blood glucose.
The 3.0 correction bolus will lower his current BG of 200 mg/dL (11 mmol/L) to his pre-meal target of 110 mg/dL
(6.1 mmol/L).
elevated blood glucose: 200 - 110 = 90 mg/dL (11 - 6.1 = 5 mmol/L)
correction bolus: 90 / 30 (insulin sensitivity) = 3.0 units
(He will add this 3.0 correction bolus to the 4.0 units of insulin that he will need for his meal bolus.
Jason will take a total bolus of 7.0 units.)
