Low limit
The low limit is the value on which the other low settings are based. The low limit
can be set from 50 mg/dL to 90 mg/dL. You can set up to eight low limits for
different periods of the day or night.
Suspend before low
The Suspend before low feature stops insulin delivery when your sensor glucose
values are approaching your low limit. This feature is intended to suspend insulin
delivery to minimize the amount of time spent low.
The default setting for the Suspend before low feature is off. Consult your
healthcare professional for the Suspend before low setting that is best for you.
If you turn on Suspend before low, then Alert on low is automatically turned on.
You also have the option to turn on Alert before low.
•If Alert before low is on, your pump alerts you when insulin delivery is
suspended. For details, see Alert before low, on page 160.
• If Alert before low is off, then Suspend before low appears on the screen, but
the pump will not beep or vibrate when insulin delivery is suspended.
WARNING: The Suspend before low feature uses the sensor glucose
value, not your blood glucose value to automatically suspend
insulin delivery. Your pump automatically suspends insulin delivery
when your sensor glucose is approaching the low limit. However
your blood glucose reading may be higher than the sensor glucose
value. This could result in hyperglycemia. Likewise, your pump may
not suspend insulin delivery because your sensor glucose is not
approaching the low limit. However, your blood glucose may be
lower than the sensor glucose value. This could result in
hypoglycemia. Always check your blood glucose and treat as
appropriate.
Suspend before low conditions
When a Suspend before low event occurs, all insulin delivery is suspended. For a
Suspend before low event to occur, both of these must happen:
• Your SG value is at or within 70 mg/dL above your low limit.
