Chapter 6: Inserting A Sensor And Starting Asensor Session; Before You Start - Dexcom G4 PLATINUM User Manual

CHAPTER 6: INSERTING A SENSOR AND STARTING A SENSOR
SESSION
You need a sensor, a transmitter, and a receiver to use your Dexcom G4 PLATINUM Continuous Glucose
Monitoring System. You also need a blood glucose meter and test strips for calibration. The blood glucose
meter and test strips are not provided in the Dexcom G4 PLATINUM System. The sensor continuously
measures and displays 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 disc in your kit. The tutorial is also available online at www.dexcom.com.
WARNING
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 our Technical
Support department at 1.877.339.2664 or 1.858.200.0200.
For patients undergoing an MRI with a retained wire broken off from a Dexcom G4
PLATINUM 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.

6.1 BEFORE YOU START

• Make sure the correct transmitter ID has been entered into your receiver (see Chapter 5, Section 5.2, The
Settings Menu). You do not need to re-enter the transmitter ID each time you start a sensor session.
• Check the expiration date on the sensor package label. The format is YYYY-MM-DD. Insert sensors on or
before the end of the expiration date calendar day.
• Follow your blood glucose meter's manufacturer's instructions to make sure you are getting accurate blood
glucose values for calibration.
• Wipe the bottom of the transmitter with a damp cloth or isopropyl alcohol wipe. Place the transmitter on a
clean, dry cloth, and air dry for 2-3 minutes.
• Make sure your blood glucose meter and receiver date and time match.
WARNING
Store the sensor at temperatures between 36° F - 77° F for the length of the sensor's
shelf life. You may store the sensor in the refrigerator if it is within this temperature
range. The sensor should not be stored in a freezer. Storing the sensor improperly
might cause the sensor glucose readings to be inaccurate, and you might miss a low
or high blood glucose value.
Review the sensor applicator picture before using a new sensor.
