Device: MiniMed™ 770G Insulin Pump
Safe Basal is an automatic function within SmartGuard™ Auto Mode and cannot be modified. The Safe Basal rate is determined by the Auto Mode feature based on your insulin delivery history. It lets you have time to perform additional actions required to ensure Auto Mode remains active.
Safe Basal delivers insulin at a constant rate to cover your basal needs. Safe Basal does not adjust insulin delivery based on your current sensor glucose (SG) values. After 90 minutes in Safe Basal, if the condition that caused the pump to transition into Safe Basal is not resolved, the pump enters Manual Mode.
When the pump is in Safe Basal, the Auto Mode shield appears gray with a white outline.
Several conditions can cause a transition into Safe Basal. The following table describes these conditions and the actions you must take to resume Auto Basal delivery.
|What to Do
|Auto Mode has been at the minimum delivery limit for 2 1/2 hours.
|Auto Mode has been at the maximum delivery limit for 4 hours.
|Your sensor might be reading lower values than your actual glucose values.
|An entered BG is 35% or more different than your current SG value.
|No SG data has been received for more than 5 minutes.
When you change your sensor, your pump switches to Safe Basal for up to 90 minutes. The pump tells you to calibrate and enter a BG for Auto Mode.
