Removing The Sensor From Its Packaging; Choosing An Insertion Site - Dexcom G4 User Manual

3.2

REMOVING THE SENSOR FROM ITS PACKAGING

The sensor is sterile in its unopened, undamaged package. Do
not use any sensor if its sterile package has been previously
damaged or opened.
• Wash your hands thoroughly and dry them.
• Carefully remove the sensor from its packaging. Look closely at the sensor to
make sure it is not damaged.
• The applicator is a single use, disposable unit. The safety lock prevents you
from accidentally releasing the needle before you are ready.
3.3

CHOOSING AN INSERTION SITE

Change the site where you place your sensor with each insertion to
allow your skin to heal.
Avoid areas that are likely to be bumped, pushed or compressed
or areas of skin with scarring, tattoos, or irritation as these are not
ideal sites to measure glucose.
Avoid injecting insulin or placing an insulin pump infusion set within
7.62 cm of the sensor in case the insulin affects the sensor glucose
readings.
Reviewing the tutorial disc would be helpful to learn how to insert your sensor.
Choose a site on your belly to place the sensor. You can choose a site above
or below your belt line. The best areas to insert your sensor are usually flat,
"pinchable," and free from where rubbing can occur such as along the waist
band and seat belt strap.
• Choose an area that is at least 7.62 cm from where you plan to inject insulin or
from where your pump infusion site is located.
• Avoid using the same spot repeatedly for sensor insertion. Never use the same
site for 2 sensor sessions in a row.
• You may need to shave the area where you plan to put the sensor so that the
adhesive patch sticks securely.
• Make sure there are no traces of lotions, perfumes or medications on the area.
