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 finger sticks 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 standalone Dexcom G4® PLATINUM receiver or your CGM enabled Animas® Vibe® Insulin Pump 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.

CGM doesn’t replace fingerstick testing; rather, it works with it. 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 G4® PLATINUM CGM Sensor, Transmitter and Receiver work with the Animas® Vibe® Insulin Pump

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. The Dexcom G4® PLATINUM Sensor that works with the Animas® Vibe® Insulin Pump is indicated for up to 7 days of wear.

It’s very important to note that interstitial fluid contains slightly different glucose values than those found in your blood, so the sensor’s job is not to tell you what your number is—that’s still the job of your meter. Instead, the sensor tracks how your glucose is behaving, which is something your meter can’t do.

About the transmitter.

The transmitter clips into place inside a plastic sensor pod that’s attached to the adhesive and sensor. It wirelessly sends your sensor-measured glucose readings to your Dexcom receiver or insulin pump.

About the CGM-enabled pump.

The 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 to see what your glucose is doing 24/7 on a high-contrast colour screen?*
  2. Do you want to be alerted to your highs 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, along with your fingerstick results, to help guide insulin adjustments?†
  5. You want a sensor that’s indicated for up to a week of wear?

*You must confirm your glucose reading with a fingerstick test before taking action.

†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.
