USAGE

Do you have a recommendation for what type of batteries to use?

MiniMed 630G insulin pump

Requires one new AA (1.5 V) battery
For best results, use a new AA lithium battery.
The pump also accepts an AA alkaline or a fully charged AA NiMH (nickel-metal hydride) rechargeable battery.
Do not use a carbon zinc battery in your pump.
Battery life is typically 7 to 21 days depending on the type of battery and whether CGM is being used.
Some features that may reduce battery life are:

  • backlight setting
  • brightness setting
  • vibrate alert type
  • remote meter use
  • high basal rates, “excessive” button pressing, bolusing and rewinding 
  • frequent sensor signal/sensor signal not found alerts (when using CGM)
     
MiniMed® Veo Insulin Pump
  • Alkaline AAA battery
  • Energizer batteries provide a very predictable time window between receiving a “low battery” warning to system loses power (an “off no power” state). This helps ensure proper battery alerts are received as your battery gets low.
  • The use of other battery brands or type may result in more variation.
  • Some features that may reduce battery life are:
    • using the backlight
    • vibrate alert type 
    • remote control & Meter
    • high basal rates –  “excessive” button pressing, bolusing and priming  
 

Pump Care Best Practices

Properly caring for your insulin pump is important for protecting its integrity and longevity.

We’ve compiled this list of “Best Practices” for pump owners based on questions from customers like you. These will help answer concerns you might have about caring for your insulin pump.

 

LOW GLUCOSE SUSPEND AND PREDICTIVE ALERT FEATURE

What is the low glucose suspend feature on the insulin pump?

MiniMed 630G insulin pump
The suspend feature (Suspend on low) is a CGM feature to help people who may experience frequent hypoglycemia, have a fear of hypoglycemia, or have hypoglycemia unawareness. If the feature is turned on, the pump automatically suspends insulin delivery for up to 2 hours when glucose levels reach a pre-determined limit.

MiniMed® Veo™
The low glucose suspend feature is a continuous glucose monitoring (CGM) feature to help people who may have a fear of hypoglycemia or hypoglycemia unawareness. If the feature is turned on, the pump automatically suspends insulin infusion for 2 hours when glucose levels reach a pre-determined threshold and, without intervention, will resume basal insulin delivery to its pre-set rate. All other sensor functions remain operational during insulin suspension.

What should I do if the suspend feature is triggered on the MiniMed 630G and the MiniMed Veo insulin pump?

If you DO NOT respond to the alarm, the pump suspends insulin delivery, sounds a siren alarm and displays “CALL FOR EMERGENCY ASSISTANCE. I have diabetes.” The pump suspends insulin delivery for 2 hours. After 2 hours, the pump resumes basal insulin delivery. If blood glucose (BG) is still low 4 hours after resuming basal, insulin delivery re-suspends. 

If you DO respond to the alarm, you can choose to Continue Suspend or Resume Basal insulin delivery. If you resume basal delivery then your pump will continue to deliver insulin. If you choose to suspend, the pump suspends insulin delivery as above. When the Suspend on Low feature is triggered the pump sirens to ensure the alarm is heard and acted upon.

When possible, you should always confirm your hypoglycemia with a meter BG test and treat it with the appropriate amount of fast-acting carbohydrate.

Why does insulin delivery stop for 2 hours and resume for 4 hours on the MiniMed 630G and the MiniMed Veo insulin pump?

The two hour period is based on clinical evidence and allows blood glucose to return to normal. The 4 hour period for resuming insulin delivery after halting it reduces the risk of rebound hyperglycemia.

On the MiniMed 630G insulin pump, what is the difference between the Alert before low, Suspend on low and Alert on low?

The low glucose features allow you to set your pump to alert if you are approaching your low Sensor Glucose limit, or to alert/suspend if you have reached your low Sensor Glucose limit.

The following table describes the low glucose alert settings.

Low Setting name                           How it works
Alert before low                              Your system alerts you any time it is predicted that your Sensor
                                                       Glucose reading will reach the low limit within 30 minutes.

Suspend on low                              Your pump temporarily stops delivering insulin if your Sensor
                                                       Glucose reading reaches or falls below your low limit.

Alert on low                                    Your system alerts you when your Sensor Glucose reading
                                                       reaches or falls below your low limit.

If you DO NOT respond to the Suspend on low alarm, the pump will suspend insulin delivery, sound a siren alarm after 2 minutes and display “CALL FOR EMERGENCY ASSISTANCE. I have diabetes.” The pump basal rate will resume in two ways:

1.      You manually restart the basal rate
2.      Insulin delivery has been suspended for 2 hours and the pump auto resumes

If you DO respond to the alarm, you can choose to suspend or resume basal insulin delivery. If you resume basal delivery your pump will continue to deliver insulin. If you choose to suspend, the pump suspends insulin delivery.

SETTING ALARMS

How do I set or change my glucose alarms limits?

MiniMed 630G insulin pump
The high and low sensor settings can be adjusted in the Sensor Settings. You can have different time periods, and glucose alerting, at different times of the day and night.
Your high glucose limit can be set between 5.6 and 22.2mmol/L.
Your low glucose limit can be set between 3.2 and 5.0mmol/L.

MiniMed® Veo™
The high and low glucose alarms have to be at least 0.6 mmol/L apart. 
If you set your high glucose limit at 10 mmol/L, then you cannot set your low glucose limit greater than 9.4 mmol/L.Conversely, if you set your low glucose limit at 2.8 mmol/L then you cannot set your high limit lower than 3.4 mmol/L.

What do the rate of change arrows indicate?

MiniMed 630G insulin pump
One arrow either up or down indicates that glucose readings have increased/decreased by approximately 1-2mmol/L over the last 20 minutes.
Two arrows either up or down indicate that glucose readings have increased/decreased by approximately 2-3mmol/L over the last 20 minutes.
Three arrows either up or down indicate that glucose readings have increased/decreased by more than approximately 3mmol/L over the last 20 minutes.
The rate of change arrows can be used to help a patient detect period when their glucose levels are rising/dropping quickly.

MiniMed® Veo™
One arrow either up or down indicates that glucose readings have increased/decreased by 0.05-0.11 mmol/L per minute.
Two arrows either up or down indicate that glucose readings have increased/decreased by 0.11-or more per minute.
The rate of change arrows can be used to help a patient detect when their glucose levels are rising/dropping quickly and act to help to prevent any severe episodes.
