6.3 CHOOSING AN INSERTION SITE
Review the tutorial disc for more help 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
usuallyat,“pinchable,”andfreefromwhererubbingcanoccur,suchas
along the waist band and seat belt strap.
• Choose an area at least 3 inches from your insulin pump infusion set
or injection site.
• 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.
PRECAUTION
• 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.
