A re-alert occurs when the initial alert has not been confirmed.
The small device which collects your glucose information from
the sensor/transmitter. Your results are displayed on the receiver
screen as a sensor glucose reading (mmol/L) and as a trend.
Alerts based on how fast your glucose levels rise/fall, and by
how much.
Radio-frequency transmission used to send glucose information
from the transmitter to the receiver.
The safety lock keeps the needle inside the applicator before
you are ready to insert the sensor. It also helps you snap the
transmitter out of the sensor pod after your sensor session has
ended.
The part of the sensor that is inserted under your skin with the
applicator. It measures the glucose levels in your surrounding
tissue fluid.
The small plastic base of the Sensor attached to your belly that
holds the transmitter in place.
A snooze time (every 15 minutes up to 5 hours) can be set in
between high and low glucose re-alerts.
The 2-hour "startup" period after you tell the receiver you
have inserted a new sensor (sensor glucose readings are not
provided during this time).
A sensor glucose reading shown on your receiver. This reading
is given in mmol/L units and is updated every 5 minutes.
The Dexcom G4 System component that snaps into the sensor
pod and wirelessly sends glucose information to your receiver.
Transmitter ID that is entered into your receiver to enable it to
communicate with the transmitter.
The small disposable component that snaps the transmitter
into the sensor pod. It is removed after the transmitter is
snapped in.
Arrows on trend graphs that indicate if and how fast your
glucose levels are changing. There are 7 different arrows that
show when your glucose speed and direction change.
