How to Properly Use the Dexcom G7 All-in-One Sensor/Transmitter: Step-by-Step Guide

Managing diabetes has become more accurate, more convenient, and more user-friendly with the latest technology available. At Allen Medical Equipment, we proudly provide North Texas patients with one of the most advanced continuous glucose monitoring systems on the market — the Dexcom G7 All-in-One Sensor/Transmitter. In this complete guide, we’ll walk you through exactly how to set up and use your Dexcom G7 for optimal diabetes management.

What is the Dexcom G7 All-in-One Sensor/Transmitter?

The Dexcom G7 is a state-of-the-art continuous glucose monitoring (CGM) device that helps individuals track their glucose levels in real time. Unlike older systems, the G7 combines both the sensor and transmitter into a single, compact unit that is discreet, simple to apply, and highly accurate.

With continuous updates every 5 minutes, trend alerts, and customizable notifications, the Dexcom G7 helps patients and caregivers make informed decisions with confidence.

Getting Started: What’s Included

When you receive your Dexcom G7 kit from Allen Medical Equipment, it includes:

  • Dexcom G7 All-in-One Sensor/Transmitter
  • Pre-loaded Applicator
  • Alcohol wipes
  • User instructions

Before starting, ensure you have your smartphone or Dexcom receiver ready with the Dexcom G7 app installed and account set up.

How to Apply and Use the Dexcom G7

1️⃣ Choose an Insertion Site

The Dexcom G7 can be applied to:

  • Upper arm (adults and children 2+ years)
  • Abdomen (adults)
  • Upper buttocks (children 2-6 years)

Tip: Always consult your healthcare provider to select the best insertion site for your individual needs.

2️⃣ Clean the Site

  • Wash hands thoroughly.
  • Clean the chosen area with an alcohol wipe.
  • Allow the skin to fully dry to ensure proper adhesion.

3️⃣ Prepare the Applicator

  • Carefully remove the applicator from its packaging.
  • Avoid touching the adhesive or sensor area to maintain sterility.

4️⃣ Apply the Sensor

  • Remove the adhesive backing.
  • Place the applicator flat against the cleaned skin.
  • Press the button to insert the sensor — insertion is quick and nearly painless.

5️⃣ Start Your Sensor Session

  • Open your Dexcom G7 app or receiver.
  • Scan the sensor code or manually enter it when prompted.
  • The sensor will begin a 30-minute warm-up period before providing glucose readings.

6️⃣ Monitor Your Glucose

Once the warm-up is complete, your Dexcom G7 will begin transmitting real-time glucose readings directly to your app or receiver. You’ll have access to:

  • Current glucose levels
  • Trend arrows showing whether your glucose is rising, falling, or stable
  • Customizable alerts for high or low levels

You can also share your data with family members or healthcare providers using the Dexcom Follow app.
