The bolus dose for high blood sugar correction is defined as how much one unit of rapid-acting insulin will drop the blood sugar. Generally, to correct a high blood sugar, one unit of insulin is needed to drop the blood glucose by 50 mg/dl.

How do I calculate how much insulin to take?

Divide the total grams of carb by your insulin-to-carb ratio. Example Let's say you plan to eat 45 grams of carbohydrate and your insulin-to-carb ratio is 1 unit of insulin for every 15 grams of carbohydrate eaten. To figure out how much insulin to give, divide 45 by 15.

What is insulin typically dosed in?

Subcutaneous regular human insulin: 0.1 unit/kg subcutaneously every 1 to 2 hours; when blood glucose is less than 250 mg/dL (14 mmol/L), give glucose-containing fluids orally and reduce insulin to 0.05 unit/kg subcutaneously as needed to keep blood glucose around 200 mg/dL (11 mmol/L) until resolution of DKA.
