Your Medtronic Guardian® CGM System allows you to customize
alerts to help improve your glucose control. Your healthcare
provider will work with you and your trainer to determine the
initial alert settings that work best for you.
In using CGM, these settings will determine how often you are
alerted. You will want to find a balance between the benefit of
receiving these alerts and any inconvenience that may be caused by receiving too many.
During the first several weeks on CGM, you and your healthcare provider may consider (i)
waiting to turn these alerts on, (ii) turning on only certain alerts, or (iii) setting these alerts
very wide. As you learn more about your glucose patterns and how to use CGM, you will be
able to adjust your alert settings to meet your individual needs.
Two alerts are the HIGH SG and lOW SG alerts, which notify you when your glucose has moved
above or below your programmed glucose limits. For example, if your HIGH SG alert is set at
250 mg/dL and your lOW SG alert is set at 70 mg/dL, you will receive an alert every time your
glucose goes above 250 or below 70.
You can set up to 8 customizable HIGH SG and lOW SG alert limits for different periods
of the day. This is especially helpful, for example, if you would like to set your glucose alert
limit differently at night to prevent frequent alerts while you sleep.
Calibration is essential for optimal sensor performance. The glucose
sensor performs best when calibrated 3–4 times per day.
CGM does
not
eliminate the need for BG meter readings (fingersticks).
You do not need to wait 6 hours (day one) and 12 hours to calibrate.
You can calibrate early, as long as your glucose is stable.
