1. A system comprising:

  • a glucometer measuring blood glucose measurements separated by a time interval;

    an insulin administration device; and

    a dosing controller in communication with the glucometer and the insulin administration device, the dosing controller including data processing hardware and non-transitory memory in communication with the data processing hardware, the non-transitory memory storing instructions that when executed by the data processing hardware cause the data processing hardware to perform operations comprising;

    receiving blood glucose measurements for a patient from the glucometer, the blood glucose measurements comprising a current blood glucose measurement measured at a current time and a previous blood glucose measurement measured at a previous time earlier than the current time, wherein an elapsed time between the current time and the previous time defines a current time interval;

    determining an intravenous insulin infusion rate based on the current blood glucose measurement and the previous blood glucose measurement;

    determining a blood glucose percentage drop based on the current blood glucose measurement and the previous blood glucose measurement;

    determining a blood glucose drop rate based on the current blood glucose measurement, the previous blood glucose measurement, and the current time interval;

    determining a next time interval from the current time until a next time of a next scheduled blood glucose measurement for the patient based on the current blood glucose measurement, the next time interval comprising a shorter duration of time than the current time interval when;

    the blood glucose percentage drop is greater than a threshold percentage drop;

    orthe blood glucose drop rate is greater than a threshold drop rate; and

    sending the intravenous insulin infusion rate from the data processing hardware to the insulin administration device in communication with the data processing hardware, and when the insulin administration device receives the intravenous insulin infusion rate, the insulin administration device configured to administer insulin to the patient intravenously using the intravenous insulin infusion rate.
