CGM Tips & Tricks

Whether you’re using the Animas® Vibe® CGM-anabled insulin pump or a CGM standalone system, here are some quick tips and tricks to help you get the most out of your CGM experience.And remember: Before you begin using the Animas® Vibe® CGM-enabled insulin pump, or anytime you have questions, review the Owner’s Booklet, Quick Start Guide, and tutorial disc provided.

Sensor Insertion

  • Flatten the Sensor adhesive before removing the adhesive backing from the bottom of the Sensor pod.
  • After placing the Sensor on your belly, rotate your fingers around the Sensor adhesive to secure the tape to the skin.
  • Using your thumb and finger, it may help to pinch up on your skin at the base of the tip of the white adhesive (using your non-dominant hand) during Sensor insertion. See Figure A.
  • Make sure you hear 2 clicks when snapping the Transmitter in place. Failing to seat the Transmitter completely may lead to a poor Sensor connection and allow fluids to get under the Transmitter.
  • Do NOT remove the Transmitter from its box until you are ready to start your initial Sensor session. Once removed from its tray, the Transmitter battery will activate within 10 minutes.

    Sensor Adhesion

    • For added adhesion, skin preparations or adhesive products (Mastisol® liquid adhesive, Skin Tac wipes) are optional.
    • If using skin preparations or adhesive products, place it on the skin in a “doughnut” shape and insert the Sensor through the clean skin at the centre of the doughnut.
    • If your Sensor patch is peeling up, you can use medical tape (such as Blenderm®, Tegaderm, IV 3000, 3M® tape) for extra support.
    • If using medical tape, only tape over the white adhesive patch on all sides for even support. Do not tape over the Transmitter or any of the plastic parts of the Sensor pod. See Figure B.
    • Do not tape under the Sensor pod or leave any substance on the skin where you insert the Sensor.

      Calibration dos and don’ts

      • Use the same BG meter for all calibrations, and quality-check BG meter to make sure it is giving accurate values for calibration.
      • Use proper technique when performing a fingerstick test. Entering the correct fingerstick BG value is critical to obtaining accurate Sensor readings. See Figure C.
      • Calibrate at any time as long as you see a CGM glucose reading or BG symbol on the Animas® Vibe® CGM Data or Trend Screen.
      • Calibrate a minimum of once every 12 hours.
      • Calibrate even if your glucose levels are rising are falling.
      • Do NOT use sampling sites other than your fingertips to get BG values for calibration. Use a blood glucose value obtained only from a fingerstick for calibration. See Figure C.
      • Do NOT calibrate if your BG is higher than 22.2 mmol/L or lower than 2.2 mmol/L.
      • Do NOT calibrate if you have taken acetaminophen, as it may falsely raise your Sensor glucose readings.

        RF Communication

        • The transmission range, without obstruction, from the Transmitter to the Animas® Vibe® is 3.6 metres (12 feet).
        • Unknown Sensor Glucose Readings or Out of Range errors are usually temporary and will correct themselves. Do not calibrate during this time. See Dexcom G4® PLATINUM example in Figure D.
        • An unsecured Transmitter can cause Unknown Sensor Glucose Readings.
        • Check that the Transmitter is properly seated in the Sensor pod if you receive this error.
        • Wireless communication does not work well through water so the range is reduced if you are in a pool, bathtub, water bed, etc.
        • RF communication problems may occur when wearing damp clothing, using electric blankets or water beds, or if in the presence of nearby metallic objects or high levels of electrical noise.

          Ending a Sensor Session

          • Peel off the Sensor pod/Transmitter from your body like a bandage.
          • Keep the Sensor pod/Transmitter attached. Place the Sensor pod/Transmitter on a hard surface and remove the Transmitter from the Sensor pod manually or by using the safety lock. See Figure E.
          • Dispose of the Sensor per local guidelines regarding disposal of blood-contacting components.
          • Do NOT dispose an active Transmitter - it is reusable. The same Transmitter is used for each Sensor session until you have reached the end of the Transmitter battery life.

            Travel Information

            • You can go through the metal detector or be “handwanded” while wearing your Sensor and Transmitter. See Figure F.
            • Do not put your Animas® Vibe® or Dexcom G4® PLATINUM Receiver through the x-ray or body scanning machines.
            • It is recommended that you notify the airport security officer that you’re wearing a CGM device and would like a full-body pat-down and/or a visual inspection.
            • If asked, advise the airport security officer that the Sensor cannot be removed because it is inserted under the skin.
            • Animas® Vibe® and Dexcom G4® PLATINUM are safe for use on commercial airlines.
