Alarm/Alerts
With the Dexcom G5 Mobile, you have everything you need to make a treatment decision: an
Alarm or Alert, sensor glucose readings, and trend arrows.
Just got an Alarm or Alert? Chances are you need to make a treatment decision quickly.
As you learned earlier, you can never turn off or change your Urgent Low Glucose Alarm,
but you can change your Alerts—including turning them off. Make sure you always get your
Alerts by keeping them on.
Even when your smart device is set to Silent, you still get notified. As a reminder, if you use
an accessory device, such as a smart watch, check your smart device and accessory device
settings so they don't override your sounds and other settings
Work with your HCP in setting optional Alert features (Chapter 12). You can repeat an Alert if
you continue to be high or low over time, or set an Alert letting you know your sensor glucose
readings are rising or falling. Alerts help you make timely decisions to help you stay within
your target range.
Your HCP can help you set your Alerts. While the default Low Alert is 80 mg/dL, setting it
lower may decrease the time before you get symptoms. Setting it higher gives you more
time. However, the higher the setting, the more Alerts you'll get.
Your High Alert default is 200 mg/dL. If you normally have a high A1C, this may result in too
many Alerts. You may want to talk with your HCP about raising your High Alert setting. If you
are tightly managing your diabetes, you may want to talk with your HCP about lowering your
High Alert setting
The Signal Loss alert lets you know your transmitter and display device are no longer talking
with each other. When there is a signal loss, you won't get a reading with a trend arrow and
won't be able to use your Dexcom G5 Mobile for treatment decisions.
Need a refresher on your Alarm and Alerts? Chapter 11 reviews all of the Alarm and Alerts,
and Chapter 12 shows you how to customize them to best fit your needs.
After receiving an Alarm or Alert, look at your home screen: What direction is your trend
arrow showing?
