Hypoglycemia prediction alert
The hypoglycemia prediction alert (Urgent Low Soon) is designed to let users know if
their glucose will be at or below 55 mg/dL within 20 minutes. In Study 1, the
hypoglycemia prediction alert (Urgent Low Soon) correctly detected when YSI glucose
fell below 55 mg/dL within 20 minutes before the event 88.8% of the time for adults
and 94.3% of the time for pediatrics. (Data not presented in table.)
