Patent ID: 8439837

Claim:
A method for establishing a critical sampling rate for a continuous glucose monitor having a continuous glucose sensor, processor, and memory, the method comprising the steps of: establishing with the processor and memory of the glucose monitor, a preferred number of measurements within a target zone, a predetermined critical threshold, and a predetermined hypoglycemic threshold, in which the target zone comprises a number of glucose measurements measured within a glucose concentration interval and within a time interval wherein said preferred number is about three; measuring with a continuous glucose sensor a plurality of glucose concentrations at a predetermined first sampling rate; calculating with the processor an actual rate of change in glucose concentration based on said plurality of glucose concentrations; modifying with the processor, said first sampling rate to a second sampling rate using a function based on said preferred number of measurements within a target zone, said predetermined critical threshold, said predetermined hypoglycemic threshold, and said actual rate of change in glucose concentration; and activating a hypoglycemic alarm to detect a hypoglycemic glucose concentration once said first sampling rate is modified to give a second sampling rate.
