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 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.
