3.00 FPU from this meal - extended bolus: 3.00 units over 5 hours.

  • Your meal has 3.00 FPUs, equivalent to about 30.0 g of carbohydrate in its effect on blood glucose.
  • You should deliver approximately 3.00 units of insulin as an extended bolus over 5 hours.
  • A meal this high in fat and protein can delay glucose absorption by up to 8 hours. Monitor blood glucose every 1-2 hours after eating.
  • Your IC ratio of 10 g/unit is central to this calculation. If your IC ratio changes, recalculate before each meal.

Next stepCombine this extended bolus with your standard carbohydrate bolus to deliver a full dual-wave bolus. Always confirm doses with your certified diabetes educator or endocrinologist.
