Glucose Alerts; High Glucose Alert - Dexcom G4 User Manual

GLUCOSE ALERTS

The Dexcom G4 System lets you create your own personal settings for how you
want the receiver to tell you what is going on. The low and high glucose alerts
will tell you when your sensor glucose readings are outside your target glucose
range. Rise and fall (rate of change) alerts let you know when your glucose
levels are changing fast (see Chapter 6, Section 6.2, Advanced Alerts). The
Dexcom G4 System also features a low glucose alarm that cannot be adjusted
or turned off and is set at 3.1 mmol/L. This is a safety feature telling you your
glucose level may be dangerously low. In addition to the alert screens that
appear on your receiver display, you can also set high and low glucose alerts
to notify you with vibrations and beeps. This feature can be helpful during times
such as sleeping, driving, exercising, or during meetings.
6.1.3

HIGH GLUCOSE ALERT

When your sensor glucose readings are at or above
your high alert level, this screen will appear with your
high glucose alert value displayed. Your receiver will
vibrate and/or beep depending on your profile setting
(see Chapter 6, Section 6.3, Alert Profiles).
When you set the high glucose alert, this level is

at 11.1 mmol/L
The receiver will continue to alert you until you press
the SELECT button to clear the alert, or until your
sensor glucose readings drop below your high glucose
alert level. You can choose to have the receiver
re-alert you after clearing the alert by changing
your snooze settings (see Chapter 6, Section 6.2,
Advanced Alerts).
