Abstract
An aspect of an embodiment or partial embodiment of the present invention (or combinations of various embodiments in whole or in part of the present invention) comprises, but not limited thereto, a method and system (and related computer program product) for continually assessing the risk of hypoglycemia for a patient and then determining what action to take based on that risk assessment. A further embodiment results in two outputs: (1) an attenuation factor to be applied to the insulin rate command sent to the pump (either via conventional therapy or via open or closed loop control) and/or (2) a red/yellow/green light hypoglycemia alarm providing to the patient an indication of the risk of hypoglycemia. The two outputs of the CPHS can be used in combination or individually.

214. A computer-implemented method for preventing or mitigating hypoglycemia in a subject, comprising:
-
receiving metabolic measurements associated with the subject from a metabolic measurement device; assessing a risk of hypoglycemia based on the received metabolic measurements;
determining an insulin delivery attenuation factor based on the assessed risk of hypoglycemia; andoutputting said insulin delivery attenuation factor to an insulin delivery device that adjusts delivery of insulin to said subject in accordance with said insulin delivery attenuation factor, if the assessed risk of hypoglycemia is above a predetermined threshold. - View Dependent Claims (215, 216, 217, 218, 219, 220, 221, 222, 238, 241)

223. A system for preventing or mitigating hypoglycemia in a subject, comprising:
-
a metabolic measurement device for obtaining metabolic measurements associated with the subject; an assessment device for receiving said metabolic measurements and assessing a risk of hypoglycemia based on the metabolic measurements; an evaluation device for determining an insulin delivery attenuation factor based on the assessed the risk of hypoglycemia, and outputting said insulin delivery attenuation factor to an insulin delivery device that adjusts delivery of insulin to said subject in accordance with said insulin delivery attenuation factor, if the assessed risk of hypoglycemia is above a predetermined threshold. - View Dependent Claims (224, 225, 226, 227, 228, 229, 230, 231, 239, 242)

232. A computer program product comprising a non-transitory computer readable storage medium having stored therein computer executable instructions for causing a computer system to prevent or mitigate hypoglycemia in a subject, said computer executable instructions comprising instructions for:
-
receiving data of metabolic measurements associated with the subject from a metabolic measurement device; assessing a risk of hypoglycemia based on the received metabolic measurements; determining an insulin delivery attenuation factor based on the assessed risk of hypoglycemia; and outputting said insulin delivery attenuation factor to an insulin delivery device that adjusts delivery of insulin to said subject in accordance with said insulin delivery attenuation factor, if the assessed risk of hypoglycemia is above a predetermined threshold. - View Dependent Claims (233, 234, 235, 236, 237, 240, 243)
