1. A method, comprising:

  • continuously monitoring a physiological condition and an automatic administration of a medication in a closed loop control operation, wherein monitoring the physiological condition comprises monitoring a signal level associated with the physiological condition;

    detecting a deviation of the monitored signal level from a predetermined threshold level;

    retrieving an administered medication level associated with a time period where the deviation of the monitored signal level occurred;

    generating a predictive signal level with a predefined predictive model by using, at least, the retrieved administered medication level and the monitored signal level;

    comparing the monitored signal level to the predictive signal level; and

    using the comparison to determine whether a condition associated with the deviation of the monitored signal level is present.
