Device: MiniMed™ 670G insulin pump (MMT-1780K)
Safe Basal is an automatic function within Auto Mode and cannot be modified. The Safe Basal rate is determined by the Auto Mode feature based on your insulin delivery history. It allows you time to perform additional actions required to ensure Auto Mode remains active. Safe Basal covers your basal needs by delivering insulin at a constant rate. Safe Basal does not adjust insulin delivery based on your current SG values.
When the pump is in Safe Basal, the Auto Mode shield appears 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. An optional setting called the Auto Mode BG alert can be set to have the pump alert you when a BG entry is required. This setting is turned on by default.
|Condition||Actions to take|
|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.||
|Auto Mode detects that your sensor might be under-reading.||
|An entered BG is 35% or more different than your current SG value.||
|No SG data has been received for more than 5 minutes.||
After 90 minutes in Safe Basal, if the condition that caused the pump to transition into Safe Basal has not been resolved, the pump will enter Manual Mode.
Note: When you change your sensor, your pump will switch to Safe Basal for up to 90 minutes. The pump will guide you through calibrating and entering a BG for Auto Mode.
