OK, Jörg,
let's try to see once more.
We thus take initial data: Actual BG (ABG), Target BG (TBG), Bread Portion (BP> or =0), and firstly calculate Insulin Dose (ID), i.e.
ID=(ABG-TBG)*p2+BP*p3.
Now if ID> or =0 then OK, but if ID<0, i.e. almost hypo but we are still in SiDiary understanding, then we must raise BP to Hypoglycemic BP (HBP):
HBP=(TBG-ABG)*p1.
Here p1=p2/p3, p2=1/("your Korrektur x'er Regel") and p3="your BE-Faktoren". By the way p2 is better than its inverse as a manual multiplication is easier a manual division. In general p1, p2, p3 are here used as factors only.
Now all cases are in our vision field and p1 is useful.
Do you see?
I'm using mmol/l (= 18.02 mg/dl) as the only BG units in my glucometer "Elta Satellit"/Russia. In general "mol" is sometimes better than "g". For example, C-peptid is equimolar to insulin. My C-peptid was equal to 0.5 ng/ml in May 2005.
I see your p2 = 1 iu/(20 mg/dl) = (18.02/20) iu/(mmol/l) = 0.9 iu/bgu.
You are right the above-mentioned parameters aren't enough for a real good therapy, but it's already good for me, if only these ones are here sorted out. I have some intestinal problems and I see the assimilability of meals is apparently changed by undergoing a treatment. In this case my p3 is changed from 1.7 iu/bu to 1 iu/bu for antibiotics treatment and to 2 iu/bu for bacteria bifidum treatment.
Thank you for your reply, Jörg.
That's all, good-bye, oder Auf Wiedersehen!
Konstantin.
