The Dexcom ONE pack of 3 is a real-time Continuous Glucose Monitoring (rt-CGM) system designed to help people with diabetes, aged 2 years and older, manage their condition more effectively. Here are some of its key benefits and usage instructions: **Benefits:** 1. **Zero Finger Pricks or Calibrations:** Dexcom ONE eliminates the need for finger pricks or scanning, even when making diabetes treatment decisions. However, if glucose alerts and readings from Dexcom ONE do not match symptoms or expectations, a blood glucose meter should be used. 2. **Real-Time Glucose Values and Trends:** The current glucose level and trend arrows are automatically updated every 5 minutes in the Dexcom ONE app on a compatible smartphone or optional receiver. This provides a full picture of glucose levels and trends. 3. **Optional High and Low Glucose Alerts:** Users can be alerted when their glucose falls outside of high and low glucose thresholds. Alert levels and notification methods (sound or vibrations) can be customised. 4. **Delay First Alert:** This feature enables users to delay their first alert until their sensor reading is at, or past, the designated alert setting for a user-specified amount of time. 5. **Exceptional Accuracy:** Dexcom ONE provides accurate readings and doesn't require any calibration to deliver these readings. **Usage:** 1. **Sensor Insertion:** Using the auto-applicator, people with diabetes or caregivers can insert the sensor and then snap in the transmitter. The sensor monitors interstitial glucose levels through a small wire. 2. **Data Transmission:** The wearable sensor sends glucose readings and trends automatically to a smart device every 5 minutes. 3. **Compatible Devices:** Dexcom ONE shares data with compatible smartphones, but an optional receiver is available for people with diabetes who may not have access to such devices. 4. **App Usage:** The Dexcom ONE app on a compatible smartphone provides glucose readings and High/Low alerts. It's available for free on Apple or Android app stores. Remember, it's always important to consult with a healthcare provider before making any changes to a diabetes management routine.
