1. A method comprising:
- determining a predictive glucose response based on prior monitored glucose sensor data and one or more exogenous factors;
detecting a condition associated with hypoglycemia including determining a level of uncertainty in a monitored glucose level based on a predicted or anticipated glucose level;
determining a probability that the detected condition associated with hypoglycemia corresponds to a hypoglycemic condition including determining whether glucose sensor data indicates a persistent low glucose level;
comparing the determined probability that the detected condition associated with hypoglycemia corresponds to the hypoglycemic condition, to a probability threshold level to confirm a presence of the hypoglycemic condition;
modifying a first medication delivery rate adjustment frequency to a second medication delivery rate adjustment frequency based on a variation in the monitored glucose level; and
determining periodically at the second medication delivery rate adjustment frequency whether to adjust a medication delivery rate.

Abstract
Methods, system and devices for monitoring control parameters in a closed loop control operation including continuously monitoring glucose level and automatic administration of a medication, detecting a condition associated with hypoglycemia, determining whether a probability of the detected condition associated with hypoglycemia exceeding a threshold level, and outputting a notification based upon the determination are provided.
