Low/High glucose Alerts tell you when your sensor glucose readings are outside your target
glucose range. Think of them as an FYI: You need to know what's happening. Rising/Falling
Alerts tell you your glucose levels are changing quickly. Their default settings are Off (see
Chapter 12 on how to turn them on).
Alerts message you with vibrations (vibrations are not available on all smart devices), visual
prompts, sounds, or a combination of all three. If your smart device is on Silent or Do Not
Disturb, you'll still get most of your Alarm and Alerts with one main exception: your Signal
Loss Alert won't notify you when your smart device is on Silent and/or Do Not Disturb.
Unlike the Alarm, you can customize your different Alerts' target range (see Chapter 12).
During your initial setup, you establish your Low and High Alert levels. As mentioned before,
this chapter is a review of the Alarm and Alerts, recommended smart device settings, and
the receiver's default Alert settings.
Chapter 12 will show you how to change their settings to customize glucose level
notifications, how you are notified, and, in some cases, how often you get notified. The
following are the defaults.
Default Alerts
Low/High Alerts
When making treatment decisions using your Dexcom G5 Mobile CGM System, it's best to
keep your Alerts turned on.
Your Low/High Alerts have the same color-coding as your trend graph screen:
• Red: Glucose levels are below your low threshold.
– Default setting of 80 mg/dL.
• Gray: Glucose levels are within your High/Low Alert levels.
– No Alerts.
• Yellow: Glucose levels are above your high threshold.
– Default setting of 200 mg/dL
Rise Rate/Fall Rate/Repeat/Signal Loss Alerts
Rise Rate and Fall Rate Alerts warn you when your glucose levels are changing rapidly, either
up or down, and look similar to the rate of change arrows. Repeat Alerts let you know if your
sensor glucose readings continue to be above or below your Alert levels.
