Before You Start - Dexcom g4 User Manual

To use your Dexcom G4 Continuous Glucose Monitoring System
you will need a sensor, a transmitter, and a receiver. You will also
need a blood glucose meter and test strips for calibration. Once
inserted and calibrated, the sensor will continuously measure
and display your sensor glucose readings for up to 7 days. The
following sections will show you how to insert the sensor and
start a new continuous glucose monitoring session.
Please review the tutorial on the CD in your kit. The tutorial is
also available online at www.dexcom.com.
Sensors may fracture on rare occasions. If a sensor breaks and no
portion of it is visible above the skin, do not attempt to remove it.
Seek professional medical help if you have symptoms of infection or
inflammation—redness, swelling or pain—at the insertion site. If you
experience a broken sensor, please report this to your local distributor.
For patients undergoing an MRI with a retained wire broken off from a Dexcom
G4 Sensor, in-vitro MRI testing did not detect any safety hazards. There was no
significant migration or heating of the wire and imaging artifacts were limited to
the area around the wire.
