75Starting a Sensor Session: Inserting Sensor, Transmitter, and Starting Your Session
Chapter 6
Let’s G5! The Basics:
Starting a Sensor Session: Inserting Sensor,
Attaching Transmitter, and Starting Your Session
6.1 Overview
Now that your display devices are set up, you’re ready to begin a sensor session. If this is
your first time inserting a sensor, you may want to watch the Dexcom G5 sensor insertion
video to get a better understanding of the steps.
The Dexcom G5 sensor insertion video is available three ways:
1. Through the app
2. Via the USB card in your Dexcom G5 receiver package
3. Online at dexcom.com:
a. Click Support tab at top of page
b. Click Education
After inserting the sensor, start the sensor warmup on your smart device and receiver. The
sensor warmup takes approximately two hours, during which time your body is getting used
to the new sensor, allowing for more accurate sensor glucose readings. Once the two-hour
sensor warmup has passed, you enter two back-to-back fingerstick measurements to
calibrate the sensor’s glucose readings with your fingerstick measurements (Calibration is
covered in the next chapter).
Make sure you give yourself enough time to finish the startup session. Remember that
your smart device’s Bluetooth needs to pair with the transmitter, which may add up to 30
minutes to your wait time. Good news is you don’t need to sit around waiting—as long as
you have your display device near, you can go about your day running errands, gardening,
personalizing the Dexcom G5 settings, whatever you choose during that time frame.
