Medtronic Minimed 770G Insulin Pump Review

The Minimed 770G is the newest CGM system that has just been approved in Canada. Aside from the same features as 670G it offers additional features new to Medtronics.

The features of 670G and 770G include:

1. Automatic Insulin Adjustment

The pump can adjust insulin based on the glucose reading from the CGM. Its auto-mode automatically adjusts basal insulin-up or down – every 5 minutes. When the glucose rises background insulin is increased and when the glucose drops, background insulin is decreased.

2. Predictive Technology

Prevents lows because of its predictive technology. When the glucose is low, the system alerts the patient; if the patient does not acknowledge with a button press, it automatically shuts off basal insulin; giving glucose time to rise.
