The receiver displays “LOW” when the most recent sensor glucose
reading is less than 40 mg/dL and “HIGH” when the most recent sensor
glucose reading is greater than 400 mg/dL.
8.2 RATE OF CHANGE ARROWS
Your rate of change arrows add detail about the direction and speed of
glucose change over the last 15-20 minutes.
The trend arrows show to the right of your
current sensor glucose reading.
Do not overreact to the rate of change
arrows. Consider recent insulin dosing, activity,
food intake, your overall trend graph and your
blood glucose value before taking action.
If there are missed communications between
the sensor and receiver during the last 15-20
minutes, an arrow may not display.
This table shows the different trend arrows your receiver displays:
