Sorry Susan, as is often the case, I wasn't being clear. Our ratios are the same, just that I find it easier to work with whole numbers. you say potato and I say potatah. The BG/ins ratio you use is 50:.2, which is the same as 250:1 or 250/1 or just in my simple mind, just 250. You also use the inverse ratios (ins/bg) or .2:50, which turns me upside down into fraction-land, or 1/250. Likewise his carb/ins ratio is 10:0.2 or 10/.2 or 50/1 or just 50 for me. Sorry for the confusion. Please don't go mad or at least don't blame me *S* my wife already does. But the numbers should add up, or at least come close to being consistent. In an ideal perfect person (like your son), let's say he started at a BG of 100 and his basal rates are perfectly adjusted to keep him there for the next 4 hours. Now he eats two 4 g glucose tabs. in less than an hour his BG will be 180 (according to your numbers below, 8g x 10points/g). Now he will need to bolus to lower his BG back to 100. How much? Well according to the ratio you gave, he will have to bolus 0.32 U (80/250) for for that extra 80 mg/dl, and in 3 hours his BG should be right back at 100. All in a perfect pumping world. Right. I've done this to check my ratios of 40:1 (mg/dl fall) per (1 U of ins), and 3:1 (mg/dl rise) per (1 g carb). You might want do this little experiment to check the ratios, if you could get him to sit still for that long. ;-) -wayne <<<<<<<Wayne can you explain that again? What does a ratio of 250 mean? I thought a ratio is expressed as "2:50" (but as usual I could be missing something here.) .2:50 for his high blood sugar ratio .2:10 in order to eat a meal 10:100 meaning 10 CHO raises him 100 points How does the math work? I never knew you were supposed to be able to relate the different ratios. I figured, the rates would be different because you are trying to achieve different sorts of work with each instance. When you bolus for a meal you are trying to prevent the blood sugar from rising too fast and too much. When you bolus for a high, you are trying to bring the blood sugar that is already too high, down. And that ratio of insulin supposedly changes depending on how high you are to begin with. When you ingest CHO for a low, you may be fighting some insulin that's remaining in your system and pulling you down so it would also depend on how much remaining insulin there is right? When you ingest CHO starting at a glucose level of 100, it's a different story (Which is why all of this drives me absolutely mad...) >>>>>>>>>>>>>>>>> ---------------------------------------------------------- for HELP or to subscribe/unsubscribe, contact: HELP@insulin-pumpers.org send a DONATION http://www.Insulin-Pumpers.org/donate.shtml
