15.2. Being Aware of Your Glucose
Warning: ALWAYS be aware of your current sensor glucose value, trust how
your body feels and do not ignore symptoms of high and low glucose. Even
though insulin delivery adjusts automatically in Automated Mode with the
goal of bringing your glucose level to your dened Target Glucose, severe
hypoglycaemia or hyperglycaemia may still occur.
If your sensor glucose values do not match your symptoms, ALWAYS check
your blood glucose using a BG meter, and consider treatment and/or Sensor
calibration if necessary. ALWAYS switch to Manual Mode if you feel you are
receiving inaccurate sensor glucose values.
• Erroneously high sensor glucose values can cause excessive insulin
delivery, leading to severe hypoglycaemia, seizure, loss of consciousness
or death.
• Erroneously low sensor glucose values can cause prolonged insulin
suspension, leading to hyperglycaemia, DKA or death.
If you are having symptoms that are not consistent with your blood glucose
readings and you have followed all instructions described in this User Guide,
contact your healthcare provider.
When you routinely view your sensor glucose values and/or check your
glucose, you can better identify when you need to make a treatment decision or
troubleshoot an issue. If you are not wearing a Sensor, it is advisable to check your
blood glucose at least 4–6 times per day (when you wake up, before each meal and
before going to bed).
Check your glucose:
• Whenever you feel nauseous or sick
• Before driving a car
• Whenever your glucose has been running unusually high or low
• If you suspect that your glucose is high or low
• Before, during and aer exercise
• As directed by your healthcare provider
When using a Sensor, if your sensor glucose values are dierent than what you
expect based on how you feel, then check your blood glucose using a BG meter
to verify your sensor glucose value’s accuracy. For example, if you feel shaky and
sweaty, which usually means your glucose is very low, but your sensor glucose
value shows as in your acceptable range, you should conrm by checking with
your BG meter.
If your blood glucose readings are veried too low or too high, consider treatment.
