How does auto mode work

Auto Mode is an insulin delivery feature designed to help people on intensive insulin therapy to achieve better control 24 hours a day. This is achieved by automatically controlling basal insulin delivery to regulate glucose levels to a target sensor glucose (SG) amount. Auto Mode uses a target SG of 120 mg/dL and the target can be set temporarily to 150 mg/dL for exercise and other events.

In Auto Mode:

  • Basal insulin is delivered based on your sensor glucose (SG) values and recent insulin delivery needs. This basal insulin delivery is referred to as Auto Basal.
  • You are still required to enter carbs when you eat and blood glucose (BG) readings to calibrate the sensor.
  • When you enter a BG over 150 mg/dL, Auto Mode may recommend a correction bolus, depending on its calculations for your insulin needs.
  • You will receive a BG required notification or alert if your pump needs a BG to enter or stay in Auto Mode.

Auto Mode depends on reliable, accurate sensor measurements and your accurate entry of carbs to deliver insulin for meals. Therefore, the basic management of the therapy requires the following activities:

  • Periodic blood glucose (BG) readings using a BG meter to calibrate the sensor. The minimum calibration is every 12 hours. For better sensor performance, it is recommended that you calibrate your sensor three or four times each day. You may also receive periodic requests from your pump for BG readings without the need for calibration.
  • Use of the Auto Mode Bolus feature to deliver boluses to cover meals, and when your pump recommends a bolus.

Note: Delivering a bolus in Auto Mode is similar to delivering a bolus with the Bolus Wizard feature in Manual Mode.
