Product Info

I. Alert performance for users ages 2 through 6
CGM enables your device to display sensor glucose readings, glucose trend arrows,
glucose trend graphs, and sensor glucose alerts (for example, High and Low Limit
Threshold alerts, High and Low Predictive alerts, and Rise and Fall rate-of-change
alerts).
The high and low limit alerts (Threshold alerts) let the user know when the sensor
glucose is at or above the high limit or at or below the low limit. Using only a high
or low limit alert may reduce the number of false alerts, but does not provide a
warning before reaching a high or low limit.
Predictive alerts notify users that their sensor glucose level may soon reach a high
or low limit setting. Users may select how early they would like to be notified
before their sensor glucose level reaches a high limit setting. The earliest warning
is 30 minutes before reaching a high, but users can reduce the amount of warning
time down to 5 minutes. Users will receive a warning approximately 30 minutes
prior to when their sensor glucose level is predicted to reach their low limit
setting. In general, the earlier the warning, the more time a user will have to react
to a potential high or low, but this also increases the potential for false alerts.
A predictive alert is simply an estimation of a future sensor glucose level compared
to the high or low limit setting. If the predicted sensor glucose value is above the
high limit or below the low limit, then a predictive alert is sounded even though
the current sensor glucose level has not crossed the high or low limit. The
predicted sensor glucose level is calculated using the current sensor glucose level,
the derivative of previous sensor glucose readings (the trend or slope of the sensor
glucose readings) and the amount of early warning duration the user selects.
The device will always alert the user when the CGM reads that the user is below
50 mg/dL, regardless of the high/low threshold and/or predictive alerts that the
user sets.
Glucose TRUE Alert Rate
The glucose true alert rate is the rate at which the blood glucose confirmed that
the CGM alert was triggered correctly. For example:
True Threshold Hypoglycemic alert ratealerted when the CGM read that the user
was below the low threshold and the user’s blood glucose was actually below that
low threshold.
