  • Methods and systems for determining an intravenous insulin infusion rate to correct hyperglycemia of a patient, to maintain euglycemia of a patient, and to prevent hypoglycemia of a patient
    Patent number: 8721584
    Abstract: Methods and systems for determining an intravenous infusion rate to correct hyperglycemia of a patient, to maintain euglycemia of a patient, and to prevent hypoglycemia are disclosed. In one aspect, a method for determining an intravenous insulin infusion rate to correct hyperglycemia of a patient includes estimating an insulin infusion maintenance rate to maintain euglycemia in a patient. Further, a relationship between a current blood glucose concentration of the patient and a target blood glucose concentration may be determined. An insulin infusion rate may be determined based on the estimated insulin infusion maintenance rate and based on the relationship between the current blood glucose concentration and the target blood glucose concentration. A glycemic response of the patient may be measured while using the determined insulin infusion rate. The insulin infusion maintenance rate is re-estimated based on the glycemic response of the patient at a previous insulin infusion rate.
