Medtronic 670G Auto-mode "BG Required"

(Jess) #1

Medtronic’s 670G auto-mode system often prompts me to enter a blood glucose value, even when the sensor is reporting a value, and it doesn’t require calibration. This seems pretty ridiculous that I have to manual enter a BG value, or retest, because auto-mode can’t just grab the value from the sensor which is already being displayed on the pump! Anytime auto-mode is stopped, you have to manually re-enter the BG value (or retest) before the pump will go back into auto-mode. While not a major problem, I find this really annoying.

I heard at my last Type 1 meeting that the new Dexcom 6 will not even need calibrations. So you might want your next pump to be one paired with the Dexcom 6 instead. (This is not for sale yet.)

@ksannie you heard that correctly, no calibration, and it and the Tandem t-Slim pump are designed to work together with the auto-suspend features. There are other features too with the intention of being a “closed loop” system.
The new Omnipod [I don’t know if it is yet available] is being designed to link with the G6.

I must say I don’t understand the “BG required” prompt either. And really weird? If I ignore it long enough it seems to go away (resets itself) or it drops out of auto mode.

I have the same questions that I have been trying to get answered. I thought that the pump was supposed to know my BG from the sensor when in auto mode and automatically determine a dosage and Give It based on an algorithm. At times I have been told it has been on its maximum dosage for 4 hours and then kicks me off auto mode and asks for another BG. I have done more finger sticks since getting this pump 5 months ago than I have done in years! I share your concern and want answers, but have yet to receive anything helpful from the help line.


I posted this in the Issues with the 670G looping thread, but also seems appropriate for this discussion:

For better or worse, when I get in a situation where I just entered a BG and the pump is asking for ANOTHER BG or “BG required to enter Auto-Mode” or stay in Auto-mode I just end up entering the sensor reading, but I do NOT tell it to calibrate. If I think the sensor number isn’t close then I’ll actually check, but this thing asks for so many BG readings throughout my typical day I’d go broke on test strips if I did them all. I get the 2 Hr Auto-Mode min delivery, BG Required one fairly often. Pretty annoying when I’m sitting pretty at 100, no rapid BG drop or rise detected and the thing’s pestering me for a reading.

Maybe one day our pumps will be as awesome as the Ronco Showtime Rotisserie Oven… “Set it and Forget it!”
