6 | Continuous Glucose Monitoring System
DexCom would like to thank you for purchasing the G4-Global Continuous
Glucose Monitoring System (G4-Global System)! When you use the G4-Global
System, you will see real-time continuous glucose readings every 5 minutes for
up to 7 days. These readings will help you detect trends and patterns in your
glucose levels. Glucose trends let you see where your glucose levels have been,
which direction your levels are headed, and how fast they may be rising
or falling.
The G4-Global System is made up of three technologies that all work together:
the Sensor, the Transmitter, and the Receiver. The Sensor is a disposable unit
that you insert into your abdomen (belly) to continuously monitor your glucose
levels for up to 7 days. The Transmitter is a reusable device that snaps into
the Sensor Pod. Your Transmitter will wirelessly send your Sensor-measured
glucose information to your Receiver. The Receiver is a hand-held device that
receives and displays your glucose information every 5 minutes.
The Receiver displays your current glucose reading and shows your glucose
trend information from the past 1-hour, 3-hour, 6-hour, 12-hour, and 24-hour
periods. You will also see adjustable High and Low Glucose Alerts, and a Low
Glucose ALARM to tell you when you are outside of your target glucose levels.
Rise and Fall (Rate of Change) Alerts will let you know when your glucose levels
are changing fast.
You can use any FDA-cleared blood glucose meter for calibration on the
G4-Global System.
