Choosing An Insertion Site - Dexcom G4 Professional User Manual

6.3 CHOOSING AN INSERTION SITE

PRECAUTIONS
• Avoid inserting the sensor in 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. Insertion in those areas might
affect sensor performance, and you might miss a low or
high blood glucose value.
• Avoid injecting insulin or placing an insulin pump
infusion set within 3 inches of the sensor. The insulin
might affect sensor performance, and you might miss a
low or high blood glucose value.
Choose a site on the belly to place the sensor. You can choose a site
above or below the belt line. The best areas to insert the 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 at least 3 inches from the insulin pump infusion set or
injection site.
• If more than one sensor is used, 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
the adhesive patch sticks securely.
• Make sure there are no traces of lotions, perfumes or medications
on the area. Clean the skin with isopropyl alcohol to remove these
products from the skin.
