Did You Know: The HIGH Sensor Glucose (SG) and LOW SG alerts notify you when your glucose reaches or goes above or below your programmed glucose limits. For example, if your LOW SG alert is set at 70 mg/dL, you will receive an alert every time your glucose reaches or goes below 70.

Important: Your glucose limits are not the same as your target glucose ranges. Work with your healthcare professional to determine your glucose alert limits.

Setting the High Repeat

Device:  MiniMed® 530G (551/751), Revel™ (523/723), 522/722, Guardian

Did You Know: After you receive and clear an alert related to high blood glucose, the alert will repeat until the condition that has caused the alert is resolved.
The High Repeat (High Snooze on a 522/722 or Guardian) feature allows you to set how frequently you want the alert to repeat after you clear it the first time. For example, if your blood glucose levels usually take one to two hours to fall after a correction bolus, you may want to set the High Repeat (High Snooze on a 522/722 or Guardian) to one or two hours to avoid unnecessary alerts.

Did You Know: Rate of change alerts notify you that your glucose levels are rising or falling at a certain rate. The RISE RATE alert can be helpful if you are prone to forgetting to take insulin or miscalculate a dose since glucose levels tend to spike significantly at these times.

Likewise, the FALL RATE alert can be helpful in protecting you when you give yourself too much insulin or do not eat enough food.
