1. A method, comprising:
- monitoring, using one or more processors, a plurality of parameters associated with a closed loop control operation including continuously monitoring a physiological condition and an automatic administration of a medication, wherein the plurality of parameters monitored includes an analyte level;
detecting an adverse condition associated with the monitored physiological condition or the automatic medication administration deviating from a predetermined safety level of medication delivery of the closed loop control operation;
initiating a non-zero pre-programmed medication delivery rate when the adverse condition is detected, wherein the non-zero pre-programmed medication delivery rate is different than the automatic administration of medication and wherein the non-zero pre-programmed medication delivery rate is based on the predetermined safety level of medication delivery;
estimating medication on board information based on the monitored administration of the medication and outputting a notification based on the estimated medication on board information;
modifying the initiated non-zero pre-programmed medication delivery rate using the estimated medication on board information;
determining an acceleration of a level of a monitored analyte change; and
updating the medication delivery rate based on the determined acceleration of the level of the monitored analyte change.

9. 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 an automatic administration of a medication, detect an adverse condition associated with the monitored physiological condition or the automatic medication administration deviating from a predetermined safety level of the closed loop control operation, initiate a non\-zero pre-programmed medication delivery rate when the adverse condition is detected, wherein the non-zero pre-programmed medication delivery rate is different than the automatic administration of medication and wherein the non-zero pre-programmed medication delivery rate is based on the predetermined safety level of medication delivery, estimate medication on board information based on the monitored administration of the medication and output a notification based on the estimated medication on board information, and modify the initiated non-zero pre-programmed medication delivery rate using the estimated medication on board information, wherein the plurality of parameters monitored includes an analyte level, and wherein the memory for storing instructions which, when executed by the one or more processors, causes the one or more processors to determine an acceleration of a level of a monitored analyte change, and update the medication delivery rate based on the determined acceleration of the level of the monitored analyte change. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
