This chapter will teach you how to view your sensor glucose
readings and trend information. The trend graph will provide
additional information that your blood glucose meter does not.
It shows your current glucose value, the direction it is changing
and how fast it is changing. The trend graph can also show you
where your glucose has been over time.
Taking acetaminophen (paracetamol) containing products (such
as Tylenol) while wearing the sensor may falsely raise your sensor
glucose readings. The level of inaccuracy depends on the amount
of acetaminophen (paracetamol) active in your body.
Your blood glucose meter and sensor measure your glucose from two different
types of body fluids: blood and interstitial fluid. Therefore, your readings from
your blood glucose meter and sensor may not match.
HELPFUL HINTS:
• The greatest benefit you receive from using your Dexcom G4 System will
come from the trending information. It is important that you focus on the
trends and rate of change on your receiver, rather than the exact glucose
reading.
• If you have difficulty reading your receiver in bright sunlight, you may
need to seek a shady location.
The blood glucose value from your blood glucose meter should
be used for treatment decisions, such as how much insulin you
should take. The Dexcom G4 System does not replace a blood
glucose meter. Blood glucose values may differ from sensor glucose
readings. The direction, rate of glucose change, and trend graph on
your Dexcom G4 System provide additional information to help with
your diabetes management decisions.
