Abstract
Methods, system and devices for monitoring a closed loop control operation including signal levels received from an analyte sensor and automatic delivery of medication at least in part in response to the received analyte sensor signals, determining whether the signal level received from the analyte sensor is associated with one of a fault condition or a potential fault condition, and dynamically adjusting a current infusion rate executed by the closed loop control operation when it is determined that the signal level from the analyte sensor is associated with one of the fault condition or potential fault condition, where medication delivery rate is adjusted to a first predetermined range when the signal level is associated with the fault condition, and adjusted to a second predetermined range when the signal level is associated with a potential fault condition, and where the first predetermined range is narrower compared to the second predetermined range are provided.

8. A method, comprising:
-
monitoring a plurality of parameters associated with a closed loop control operation including continuously monitoring a physiological condition and automatic administration of a medication; detecting an adverse condition associated with the monitored physiological condition or the medication administration deviating from a predetermined safety level of the closed loop control operation; and activating a predetermined safety level threshold for medication delivery such that the level of medication administration in the closed loop control operation does not exceed the predetermined safety level threshold. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 28, 29, 30, 31)

18. A device, comprising:
-
one or more processors; and a memory operatively coupled to the one or more processors, the memory for storing instructions which, when executed by the one or more processors, causes the one or more processors to monitor a plurality of parameters associated with a closed loop control operation including continuously monitoring a physiological condition and automatic administration of a medication, detect an adverse condition associated with the monitored physiological condition or the medication administration deviating from a predetermined safety level of the closed loop control operation, and activate a predetermined safety level threshold for medication delivery such that the level of medication administration in the closed loop control operation does not exceed the predetermined safety level threshold. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 32)

33. A method, comprising:
-
monitoring a plurality of parameters associated with a closed loop control operation including continuously monitoring a physiological condition and automatic administration of a medication operating within a predetermined safety range of the closed loop control operation; detecting a signal dropout condition of an analyte sensor monitoring the physiological condition; and activating a predetermined safety level threshold for medication delivery such that the level of medication administration is modified to not exceed the predetermined safety level threshold within the safety range of the closed loop control operation. - View Dependent Claims (34)
