First few months on 670G: Letting Go to Gain Control

I used to a professional photographer. I was lucky enough to work with the best professional SLR cameras and lenses, and what I loved about using them was the control. Fuzz out the background or make it sharp as a tack with aperture adjustment. Freeze the motion or let it blur by changing shutter speed. My colleague used to call Auto Mode on the camera “Bonehead Mode”, professing that only amateurs and hacks used it. I wasn’t quite as adamant as him, as I saw the value of “Bonehead Mode” for certain situations, and I appreciated the sophisticated technology that made it work so well.

670G in Auto Mode: Forget What You Know about Pumping

As I drove to my training appointment, ready to put the 670G into Auto Mode for the first time, I reflected on my past week in Manual Mode. The Suspend Before Low feature was a real winner with me, cutting off my basal delivery before I went low. I’d also noticed a big improvement in the accuracy of the sensor, giving me confidence to let the pump take over control in Auto Mode.

670G Week One: Manual Mode

In my last blog post I told you that I decided to try the Medtronic 670g. Even though being on an insulin pump hadn’t improved my glycemic control in the previous 9 months, I still held out hope for this new pump. My insulin needs didn’t follow a pattern that either I or my doctors could get a handle on, and I was curious whether having the ‘hybrid closed loop system’ take over and make its own decisions minute by minute would do the trick.

More Reluctance by SugarVal

My last post told you about my decision to go on an insulin pump after 13 years as a Type 1 with steadily rising A1Cs, scary low blood sugars, and frustrating highs. My timing couldn’t have been better. The Medtronic 670g ­– the world’s first FDA approved pump to use information from its continuous glucose monitor to make basal insulin adjustments – was on its way to market.
