Hi all. Checking in here, sorry for being away but I’ve been kinda busy the last week.
I think the constructive advice on this thread is very useful. Definitely work with your Medtronic trainer/CDE on your setting if you can, and can reach them. Unfortunately for me my Medtronic trainer and CDE where my endo works have been “out to lunch” so to speak, and rather than offer suggestions/advice have offered nothing.
Ok, so much for the ranting on that. I am, after 1 month in Auto Mode, having great success thanks to a lot of advice and guidance from 670G Facebook groups.
The biggest challenge with transitioning to Auto Mode, in my opinion, is that what we understood AIT (active insulin time) and CR (carb ratio) to be before is NOT the same in Auto Mode. Essentially, in Auto Mode, those settings influence the aggressiveness of how the Auto Mode algorithm behaves.
There is only one AIT setting so that’s where I began tweaking things (lowering my AIT from 3 to 2 hours) since it was easiest. Currently my AIT is 2 hours. Making that change improved things quite a bit, but it was still not optimal since I only had one CR (carb ratio) setting and it was 10 and not doing the trick.
So I began (myself) tweaking down my CR, setting up multiple CRs for different time ranges of the day - and things improved tremendously. I made these changes using my Carelink 670G data (especially the assessment report), and continuously monitoring my pump’s 24 hour trend graph to see what patterns were happening at different times of the day.
That all took awhile, and a lot of patience…so work with whatever help you can get from Medtronic, your CDE, and endo to improve things gradually. It will take time, at least a month or so before you get satisfied with your results.
Also - make sure you are inserting your sensor in body locations where you are getting the best most accurate results. My abdomen did not work well for me. I currently use back of my arm (the flubby part) and sides of my calf (lower leg) and am getting fantastically accurate SG results as compared to blood sugar testing. Can’t compare this with the Dex since I never had an opportunity to try it (although I tried before going on the 630G/670G). But I am completely satisfied with SG accuracy with the 670G.
