If sensor glucose (SG) reaches your low limit, insulin delivery will be stopped.
You will always receive a message and alarm when this occurs.
You will have 10 minutes to respond before the pump begins to siren and emergency message appears.

Suspend before low event:

To help keep sensor glucose (SG) from reaching your low limit, insulin delivery will be stopped if SG is:
  • At or within 70 mg/dL above the low limit.
  • Predicted to be approaching the low limit in 30 minutes.
If Alert before low is on, you will receive an alert when insulin is suspended.

Alert on low during Suspend before low:

If insulin delivery has stopped due to Suspend before low, SG may still reach your low limit.
You will always be alerted when this occurs.
You will have 10 minutes to respond before the pump begins to siren.

Automatic basal resume based on sensor glucose (SG) value:

During Suspend before low or Suspend on low, basal insulin will automatically resume if:
  • SG is above the low limit and trending upward.
  • Insulin has been suspended by low management for at least 30 minutes.
If Resume basal alert is on, you will receive an alert when this occurs. Remember, you can manually resume basal insulin at any time.

Automatic basal resume due to 2 hour maximum suspend:

During either Suspend before low or Suspend on low, if basal insulin is not resumed due to SG values, it will automatically resume after 2 hours.
You will always receive an alert when you reach the 2 hour maximum suspend time, even if the Resume basal alert is set to Off. Remember, you can manually resume basal insulin at any time.

Low management suspend unavailable:

Once basal insulin resumes following either Suspend before low or Suspend on low, there will be a period of time when low management suspend is unavailable. This will most often be 30 minutes if you respond to the suspend alarm, but can be up to 4 hours. See Suspend before low in your insulin pump user guide for more specific information about this unavailable period.
