A method comprising: administering a treatment non-invasively at a specified level to a patient; after administration of the treatment has begun and while continuing to provide some level of treatment, temporarily increasing or decreasing the treatment relative to the specified level and returning to the specified level after the temporary increase or decrease, wherein the temporary increase or decrease in the treatment is initiated independently of a change in a parameter indicative of the underlying physiological state of the patient associated with the treatment; non-invasively measuring the parameter associated with the treatment; evaluating the measured parameter value to determine whether the temporary increase or decrease in the treatment is correlated with the measured parameter value; and providing a notification when the temporary increase or decrease in the treatment is not correlated with the measured parameter value within a predetermined period of time after initiation of the temporary increase or decrease; and providing a notification that the treatment is being delivered when the temporary increase or decrease in the treatment is correlated with the measured parameter value.
