1. A method implemented by a processor of a monitoring device including sensor electronics coupled to only one glucose sensor, the method comprising:
receiving measurement data from the sensor electronics indicative of a glucose concentration measured by the only one glucose sensor and causing display of the glucose concentration on a user interface together with a first visual indication that the monitoring device is operating in a first decision support mode, the first decision support mode including the monitoring device controlling insulin dosage by an insulin pump coupled to the monitoring device;
evaluating a clinical usability of the measurement data and determining that a glucose level indicated by the measurement data fails to satisfy a clinical usability threshold in response to the glucose level satisfying a 400 mg/dL high threshold glucose value for the only one glucose sensor or in response to the glucose level failing to satisfy a 40 mg/dL low threshold glucose value for the only one glucose sensor; and
in response to the glucose level satisfying the 400 mg/dL high threshold glucose value for the only one glucose sensor or in response to the glucose level failing to satisfy the 40 mg/dL low threshold glucose value for the only one glucose sensor, automatically transitioning the monitoring device to a second decision support mode and modifying the user interface to display a second visual indication that the monitoring device is operating in the second decision support mode, the second decision support mode preventing the monitoring device from calculating an insulin dosage amount or controlling insulin dosage by the insulin pump, wherein the first visual indication further indicates that the glucose concentration is useable for clinically reliable insulin dosing and the second visual indication further indicates that the glucose concentration is not useable for clinically reliable insulin dosing, and further indicating an expected duration that the monitoring device will be operating in when operating in the second decision support mode.
