Getting Started
with Continuous Glucose Monitoring
for the MiniMed® 530G with Enlite®
CGM Foundations
WARNING: The Threshold Suspend feature will cause the pump to temporarily suspend insulin delivery for two hours when the sensor glucose reaches
a set threshold. Under some conditions of use the pump can suspend again
resulting in very limited insuln delivery. Prolonged suspension can increase
the risk of serious hyperglycemia, ketosis, and ketoacidosis. Before using the
Threshold Suspend feature, it is important to read the Threshold Suspend
information in this Getting Started Guide and the MiniMed 530G` System
User Guide and discuss proper use of the Threshold Suspend feature with
your healthcare provider.
Record safety information from your healthcare provider:

Continuous Glucose Monitoring System Components
Section 1: Continuous Glucose Monitoring
System Components
Your MiniMed 530G with Enlite includes 3 key items:
1
Glucose Sensor The Enlite® sensor measures glucose levels in the body.
2
Transmitter The MiniLink® transmitter connects to the glucose sensor and
sends glucose readings to your insulin pump/CGM monitor.
It is recharged and stored in the MiniLink charger when not
in use.
3
Insulin Pump/CGM monitor The MiniMed® 530G insulin pump displays glucose readings.
Other items include: Enlite

The transmitter must be within 6
feet of the insulin pump in order
to communicate sensor readings.

“Insulin pump and RF accessories”
or “RF interference from other
devices” sections in the MiniMed
530G System User Guide.

Sensor Glucose and Blood Glucose
Section 2: Sensor Glucose and Blood Glucose
Your BG meter measures glucose levels in your blood while your glucose sensor measures glucose in
the uid surrounding the cells of your tissue. This uid is called interstitial uid.
Most of the time, glucose travels to your blood rst and then to your interstitial uid. Because of how
glucose moves, your BG meter readings and your sensor glucose readings will rarely match exactly
but should be close. This dierence is normal and should be expected.
However, when glucose levels are rising or falling quickly, you should expect to see a larger difference
between your BG meter readings and the sensor glucose readings. Examples of times when this larger
dierence may occur include:
• When or arrows appear on your pump screen
• After meals or after taking a bolus of insulin
IMPORTANT Sensor glucose is not the same as blood glucose. Your sensor glucose reading will
rarely match your BG meter reading.
Sensor glucose values should not be used to make diabetes treatment decisions. Always conrm
your blood glucose with a BG meter rst.
If you “feel” that your glucose is high or low, but your sensor glucose does not match your
symptoms, always test your blood glucose using your BG meter.

Trends
Section 3: Trends
When using CGM focus on what matters, the trends - the direction and the speed of the sensor glucose
readings and graphs. Pay less attention to each individual glucose number.
Example of a Sensor Glucose Trend Graph
Sensor Glucose Graph
Trend Arrow
Sensor Glucose
Reading
Your insulin pump screen will display 3-hour, 6-hour, 12-hour, and 24-hour glucose trend graphs. The
most current part of the graph appears on the far right side of the graph display.
There are times you may see one or two arrows next to your sensor glucose reading. Arrows indicate that
your sensor glucose has been changing rapidly:
or means your glucose has risen or fallen by 2 or more mg/dL per minute
or means your glucose has risen or fallen by 1-2 mg/dL per minute
When might you see your glucose trending up or down?
You may notice that after eating, giving a bolus, or when
exercising your glucose may begin to rise or fall.

Section 4: Personalize Alarm and Alerts
Your CGM settings will be most benecial to you if they are personalized for your needs. Personalizing
alerts means that all or some settings will be programmed during your CGM training but can be changed
to better meet your needs as you learn more about the information your CGM provides. Your healthcare
provider will work with you and your trainer to determine your initial settings and help with adjustments.
There are ve main categories of alarm and alerts that you can personalize:
• High and Low Glucose Alerts
• Predictive Alerts
• Rate of Change Alerts
• Threshold Suspend Alarm
• Calibration Alerts
Low and High Glucose Alerts
Low and high glucose alerts notify you when your sensor glucose readings have reached or moved
below or above your programmed glucose limits. You can set up to eight customizable Low and High
Glucose Limits for dierent periods of the day or night. You may set either the low or high limit or both.
The Low Glucose Limit can be set from 40 to 390 mg/dL. The High Glucose Limit can be set from 50 to
400 mg/dL.
In order to temporarily silence or “snooze” repeated glucose alerts, the High and Low Repeat are set for
the amount of time when you are reminded that your sensor glucose is still above or below your selected
glucose limits. The Low Repeat can be set from 5 minutes to 1 hour. The High Repeat can be set from 5
minutes to 3 hours. High and Low Repeat will also apply to other CGM settings (Rate of Change and Predictive Alerts and Threshold Suspend alarm which are discussed next).
While sleeping...
Michael wants his CGM to alert him if his sensor glucose falls too low
so his doctor instructed him to set his Low Glucose Limit to 80 mg/
dL and leave his High Glucose Limit o to prevent too many alerts.
During the day when he’s awake his Low Glucose Limit is set to 70
mg/dL as he is able to sense when his glucose is low. Michael and his
doctor agree that these settings work best for him.
Low Glucose Limit and Threshold Suspend may be programmed at the same or dierent settings.

Glucose Limit in order to prevent frequent inconvenient alerts. You can still view your
glucose readings on your pump even if your limits are not set.

Predictive Alerts
Predictive Alerts can warn you up to a half hour before you reach your chosen High or Low Glucose Limit.
With Predictive Alerts you can be made aware of potential highs and lows even before they occur. You
may set a Predictive Low, Predictive High, both or neither. The Predictive Alerts can be set from 5 to 30
minutes.
While at work...
John is very busy and with customers all day. Sometimes
he receives Low Sensor Glucose alerts while working. His
doctor has decided that setting the Predictive Low Alert to 30
minutes can notify him 30 minutes before his sensor glucose
value has reached his programmed Low Glucose Limit of 70
mg/dL.
To set Predictive Alerts:

Rate of Change Alerts
Rate of Change Alerts tell you when your glucose is changing rapidly. These alerts are useful for
understanding how quickly your glucose levels are aected by meals, insulin, and physical activity (such
as forgetting to bolus or giving yourself more insulin than you needed) and to recognize potentially
dangerous sensor glucose changes before they become a problem. You can set a Fall Rate, Rise Rate, both
or neither. The Rate of Change Alerts can be set from 1.1 to 5.0 mg/dL/minute.
NOTE: Your healthcare provider may determine that using the Rate of Change Alerts are
more helpful when notifying you of extreme changes in your sensor glucose. Otherwise,
setting the rate too low may cause you to receive too many alerts when you may not need
them such as after every time you eat causing your sensor glucose values to rise quickly.
While exercising…
Mark sometimes experiences low glucose when he is playing tennis.
His doctor has determined that using the Rate of Change Alert may
be helpful. His doctor has instructed him to set his Fall Rate to 4 mg/
dL/minute. Now when his pump noties him that his sensor glucose is
falling rapidly and is also trending towards his Low Glucose Limit of 70
mg/dL Mark is prepared to take action sooner.
