Questions and answers
The mom set a high ceiling of 300. How do I get to an actual number and not a "high" reading
You can adjust the high glucose alert value on the Dexcom G4 by following these steps:
1. Press the button to select “High Alert.”
2. Press the UP or DOWN button to highlight “On/Off” and press the SELECT button to set this option.
3. Press the LEFT button to return to the previous screen.
4. Press the DOWN button to highlight “Level.”
5. Press the SELECT button and then use the UP or DOWN button to adjust the high glucose alert value.
6. The high glucose alert value can be set between 6.7 and 22.2 mmol/L in 0.1 mmol/L increments.
7. Press the SELECT button to confirm the new setting.
This adjustment allows you to set a specific threshold instead of receiving a general "high" reading.
