Minimed 780g user here, it is not perfect. For a true closed loop we need a system that can give glucagon as well.
The current closed loop only gives you insulin to lower your blood glucose. When it gives too much it wakes you up and asks you to treat it.
You also have to accurately count carbs of meals you eat, enter when you exercise.
The sensors are also not quite reliable so sometimes it freaks out and you calibrate and go manual.
For a closed loop we need insulin and glucagon in conjunction to keep the bg stable without user intervention.
- jamesgill 1mo agoAll closed loop systems require human action--maintenance,filling reservoirs, changing sites, dealing with the inherent variation of CGMs, estimating carbs, etc. even if glucagon delivery were on board (it's being worked on). But most are generally providing insulin delivery in real time, based on CGM data. Also, I agree--glucagon would be a useful thing onboard for T1d, but not really for T2d, because (as you know) the essential problem there is highs, not lows. And I definitely agree about CGM accuracy: most people don't know that there's a significant margin of error in all CGMs. It's 'close', but not precise. I'm a parent of a T1d kid.
