11.3 Alarm and Alerts
As part of managing your diabetes, you learned how to read your Trend
screen and how to enter Events. In this chapter, you’ll learn how Alarm and
Alerts can keep you safe from severe lows or highs.
Depending on your display device, you can customize how you receive your
Alarm or Alerts.
What Is an Alarm?
While there are a variety of Alerts, there is just one Alarm : the Urgent Low
Glucose Alarm (Alarm), which is set at 55 mg/dL. The Alarm will repeat every
5 minutes until you clear the Alarm (see Chapter 12 on how to customize the
sounds). If you clear the Alarm and your sensor glucose readings do not go
over 55 mg/dL in the next 30 minutes, you get another Alarm.
Unlike Alerts, the Urgent Low Glucose Alarm setting can’t be changed or
turned off.
Think of it as a safety net: your glucose level is dangerously low—
pay attention now!
What Are Alerts?
An Alert is a message telling you your glucose trend levels need attention.
Low/High Glucose Alerts tell you when your sensor glucose readings are
outside your target glucose ranges. 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).
