I don't find the Medtronic solution to be that off. But the closed loop solution can't raise your blood sugar, it can only lower it. It only has insulin which it can dial back or increase. The real danger would be if it detected you very high and then tried to rapidly decrease it.

The FDA approved systems do have safeties in there that alarm persistent highs or on any lows. They also won't provide more basal than a multiple of the pre-configured setting you have.

The biggest thing for me was the 780G alarms less than 680G when there is nothing that I actually want to do to change it. Waking up all the damn time is no fun.

Ahh you are right, I had the situation reversed in my head. It would be the false high reading that would be the issue.

That is good to know there are some safeguards in place to prevent an over-correction.

And I agree about the constant wake-ups. The Dexcom system will sometimes not stop alerting when it detects a low, even if she has taken glucose tabs and knows it will be taken care of. If she doesnt interact with the notification it continues to alarm every 15 minutes or so. There is a recompiled APK for the dexcom apps that changes some of the notification behaviors but she hasnt needed to use that recently.
