【Alarm System Description】
The CGMS has a comprehensive safety system to check if abnormal situations
require immediate attention. The system will send notification alarms using sound,
LEDs, or vibrations as well as provide information on the PDA display.
The CGMS only contains medium and low priority alarms – no high priority
alarms (as defined by ISO standards).
The low priority prompt message may be a physiological status alarm message
(hyperglycemia alert) or a technical alarm/message. When such an alarm is triggered,
it will not have a negative impact on the user immediately, but the user needs to pay
attention to such information and make decisions to restore the blood sugar to the
normal range or ensure the real-time continuous glucose monitoring system
continues to be reliable.
