Dexcom G5x System User Guide
25
The G5x’s trend and pattern information is based on a series of sensor
glucose readings taken over a period of time.
Work with your healthcare professional and create a game plan on how to
best use your trend and pattern information in managing your diabetes.
Contraindications
Contraindications let you know when not to use the G5x; you may hurt
yourself or damage the system. Remember, if used during certain situations,
the risk of use may clearly outweigh any potential benefit. Within the chapters,
contraindications are in purple boxes.
MRI/CT/Diathermy
Don’t wear the system (sensor, transmitter, and receiver) before Magnetic
Resonance Imaging (MRI), Computed Tomography (CT) scan, or high-
frequency electrical heat (diathermy) treatment.
The system hasn’t been tested during MRI, CT scans, or with diathermy
treatment. Magnetic fields and heat could damage the components, stopping
sensor glucose readings or Alarm/Alert notifications. Without sensor glucose
readings or Alarm/Alert notifications, you might miss a severe low or high
glucose event.
Medications
Taking medications with acetaminophen (such as Tylenol or Excedrin
®
Extra
Strength) while wearing the sensor may falsely raise your sensor glucose
readings. The level of inaccuracy depends on the amount of acetaminophen
active in your body and is different for each person.
