1. A method for maintaining glycemic control in a patient in need thereof, comprising:
- deploying an equilibrium glucose sensor within a blood vessel in the patient, wherein the equilibrium glucose sensor comprises a fluorophore and a glucose binding moiety;
coupling the sensor to a monitor that displays patient'"'"'s blood glucose concentration;
andmanually administering a blood glucose regulator when the blood glucose concentration varies outside of a predetermined concentration range, wherein the blood glucose regulator is administered in an amount sufficient to return the blood glucose concentration to within the predetermined concentration range, thereby maintaining glycemic control.

Abstract
A method for achieving tight glycemic control in a patient in need thereof is disclosed. The method comprises deploying an equilibrium glucose sensor within a blood vessel in the patient, coupling the sensor to a monitor that displays the blood glucose concentration, and administering a blood glucose regulator when the blood glucose concentration varies outside of the predetermined concentration range. The blood glucose regulator is administered in an amount sufficient to return the blood glucose concentration to within the predetermined concentration range, thereby achieving tight glycemic control.

1. A method for maintaining glycemic control in a patient in need thereof, comprising:
-
deploying an equilibrium glucose sensor within a blood vessel in the patient, wherein the equilibrium glucose sensor comprises a fluorophore and a glucose binding moiety; coupling the sensor to a monitor that displays patient'"'"'s blood glucose concentration; and manually administering a blood glucose regulator when the blood glucose concentration varies outside of a predetermined concentration range, wherein the blood glucose regulator is administered in an amount sufficient to return the blood glucose concentration to within the predetermined concentration range, thereby maintaining glycemic control. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method for maintaining glycemic control in a patient in need thereof, comprising;
-
providing an analyte sensor capable of simultaneously measuring blood glucose concentration and blood pH, the analyte sensor comprising an indicator system disposed along a distal end portion of an optical fiber, wherein the indicator system comprises; a fluorescent dye that exists in at least first and second different forms depending on pH, wherein the different forms can be distinguished based on their respective first and second emissions, and a glucose binding moiety operably coupled to the fluorescent dye, wherein glucose binding causes an optical change in either in a fluorescence emission intensity or a fluorescence emission lifetime, wherein the optical change is related to the blood glucose concentration; wherein a ratio of said first and second emissions is independent of the blood glucose concentration; and deploying at least the distal end portion of the analyte sensor in the patient; coupling the analyte sensor to a controller configured to monitor the emission signals, determine blood glucose concentration based on the optical change, determine blood pH based on a ratio of the acid and base emissions, and perform real-time correction of the blood glucose concentration for changes in blood pH; and administering a blood glucose regulator when the blood glucose concentration varies outside of a predetermined concentration range, wherein the blood glucose regulator is administered in an amount sufficient to return the blood glucose concentration to within the predetermined concentration range, thereby maintaining glycemic control.

33. A method for maintaining glycemic control in a patient in need thereof, comprising:
-
deploying an equilibrium glucose sensor in the patient, wherein the equilibrium glucose sensor comprises a fluorophore and a glucose binding moiety and wherein the equilibrium glucose sensor is configured to generate a continuous signal related to a blood glucose concentration and a rate and direction of change in the blood glucose concentration; coupling the sensor to a monitor that displays a rate and direction of change in the blood glucose concentration; determining based on the rate and direction of change in the blood glucose concentration whether intervention is warranted; and intervening if warranted by administering an amount of a blood glucose regulator sufficient to prevent the blood glucose concentration from varying outside a target range, thereby maintaining glycemic control. - View Dependent Claims (34)
