An introduction to CGM

Continuous Glucose Monitoring (or CGM) systems measure your interstitial glucose levels 24 hours a day to reveal a complete view of glucose highs, lows and rates of change over time.

Unlike fingerpricks that give a number for a single point in time, CGM provides dynamic glucose information by showing you, every 5 minutes, where your glucose is, where it’s going and how fast it’s getting there.

About CGM

With CGM, a small sensor inserted beneath your skin transmits glucose readings to either your Dexcom G5 Mobile System or your Animas Vibe Insulin Pump that’s integrated with Dexcom G4 PLATINUM every 5 minutes. You can see if your glucose is going up or going down and how fast it’s getting there and also view your trends across various blocks of time.

The Dexcom G5 Mobile System gives you the freedom to view your results directly on your compatible mobile device or receiver without the need for confirmatory fingerprick testing.* The idea is to use CGM to determine the direction your glucose is headed and the rate of change.

Here’s a closer look at how the Dexcom G5 Mobile System works.

About the sensor.

The sensor is a wire inserted underneath your skin with the help of an insertion device and held in place with adhesive, similar to the way an insulin pump infusion set is attached.

It continuously reads the glucose levels in the fluid in your tissues (called interstitial fluid). Sensors are disposable. Dexcom sensors are approved for 7 days of wear.

About the transmitter.

The transmitter clips into place inside a plastic sensor pod that’s attached to the adhesive and sensor. It sends your sensor-measured glucose readings to your Dexcom receiver, compatible smart device (with Dexcom G5 Mobile) or insulin pump (Dexcom G4 PLATINUM only).

About the CGM-enabled pump.

The Dexcom CGM-enabled Animas Vibe Insulin Pump displays your glucose trends right on the screen, so you can see what’s happening any time you want after the two-hour start-up period.† It also has customised alerts that can tell you when you’re going high or low.

Is CGM right for you? Here are some things to think about.

  1. Do you want the choice to see your glucose data right on your mobile phone, Dexcom receiver or Animas Vibe Insulin Pump?
  2. Do you want to be alerted to yours or your loved ones high and lows?
  3. Do you want the safety of a hypo alert that’s fixed at 3.1 mmol/L?
  4. Do you want to use the information that CGM provides to help guide insulin adjustments?†
  5. Do you want a sensor that’s indicated for up to a week of wear?

Find out more about the Dexcom G5 Mobile System and consult with your healthcare professional to see if this system is right for you.

 

†Glucose values are not visible during the 2-hour start-up period. Always refer to your healthcare professional team for treatment and insulin adjustment decisions.

*If your glucose alerts and readings do not match your symptoms or expectations, you should obtain a fingerprick. A minimum of two fingerpricks a day are required for calibration.
