I found an article which helped me and want to share it with you here. It gave me a good reference starting point to calculate my insulin sensitivity and carb ratio. Here’s a snippet from the page (TDD is the average total daily dosage of insulin prior to starting pump therapy):

“To calculate the sensitivity to insulin (ie, the amount by which 1 unit of insulin will decrease the patient’s blood glucose level), divide 1800 by the TDD. To calculate the initial carbohydrate ratio (the number of grams of carbohydrate that 1 unit of insulin will “cover”), divide 500 by the TDD. The formula for the amount of a correction bolus (administered to correct an elevated blood glucose level) is: [(current blood glucose level) - (target blood glucose level)] ÷ (insulin sensitivity).”
