Treatment decisions should not be based solely on results from
the G4-Global System. You must confi rm System readings with
a fi ngerstick reading on a blood glucose meter before making
therapeutic adjustments.
You must update G4-Global System calibration every 12 hours at
a minimum. The performance of the System when calibrated less
frequently than every 12 hours has not been studied.
The G4-Global System also lets you enter information about your meals, insulin,
exercise, and health. That way you and your Diabetes Management Team
can view a bigger picture of your diabetes management plan. Your Diabetes
Management Team can transfer this information to the DexCom Studio
®
Accessory Software to see how you are doing over a long period of time.
