Insulin timings (2022)

Different insulins have effect (and get used up) at different speeds, and modelling this is important for accurate calculation of subsequent insulin doses. Some automated insulin delivery (AID) systems try to determine this themselves (e.g. CamAPS has nowhere for us to tell it which insulin we’re using) and some (e.g. Medtronic and Control-IQ) seem to …

Quinquennial looping!

What’s a quinquennial? A 5-year anniversary. Yes, it was a whole 5 years ago I finally set up my “DIY” closed-loop. I’m obviously still using it, although there’ve been lots of changes along the way. Both in terms of improvements in clinical results and in terms of quality of life. What’s changed in the technology? …

May 2022 data snapshot

Last month I mentioned that I had modified the parameters I was using for the insulin activity/IOB modelling in my AID/loop system. Specifically, for Lyumjev and for Humalog I’m now using 9 hours in the exponential IOB model. I showed statistics from two 4-week samples of Lyumjev, and then a 7-day sample using this timing …
