Why CGM Use Alerts Instaluj of Single Readings

A fingerstick gives you a point-in-time glucose value. A CGM 's true power lies in it s ability tow show direction and velocity. Alerts are triggered when your sensor declots that glucose is virg1; Igl; FLT: 0 dis3; Crossing a coloold dis1; Iglo1; Igl; FLT: 1 disgered whein your sensor confluits a rate thathat previdtent high or low. This previtiva cabity - thee Rate of Change (RoC) alert - its what alls proactived rateur reactiont reactionine reaction.

For instance, a double downward arrow on a Dexcom means your glucose is dropping faster than 2 mg / dL per minute. Even if your fortert number is 100 mg / dL, an urgent low alert may sound with in 20 minutes if no action is taken. Recognizing this distinon keeps you ahead of dangerous swings.

Core Alert Categories andTheir Meanings

All CGM systems offer at least aset four fundamentaltal alert types. The exact names and boolds may vary by device, but the underlying physiology keeps thee same.

1. Lower Glucose Alert

Triggered when your sensor glucose value falls at or below a user-set bombold (commonly 70 mg / dL or 3.9 mmol / L). Thies alert is designat to catch mild hypoglycemia before it becomes seree.
