His numbers need to be between 4-7 and he is coming up on days around 11, so what would his correction amount be??
If you look at CarbsRok's msg to you on the thread you will see that she has tried to explain the principles behind carb counting using a ratio and how to understand the correction factor.
You say that your son should have bg levels between 4 - 7mmol but using the carb ratio set by your dsn, his bg levels are around 11mmol. I take it that this bg level (11mmol) is before your son is due to eat a meal again (4hrs) or is this level 2hrs after he has eaten?
To work out a correction amount of insulin, you need to take away your target bg level (6mmol) away from the higher bg level you get (11mmol) that leaves you with 5mmol. If 1u of insulin lowers his bg by 10mmol, then 0.5u will lower by 5mmol. So, you would need to use a correction dose of 0.5u to lower his bg level back to the target of 6mmol.
Are you sure that you are working out the exact amount of carb that your son is eating only if you are not, then using the carb ratio that your dsn thinks you need to use, is not going to work very well. Also, if you are working out the carb accurately, the higher bg level that your son is getting probably means that the insulin to carb ratio needs adjusting so that your son starts to get lower bg levels. There is a lot of trial and error involved in calculating carb ratios correctly...... means doing a lot of bg tests, writing the carb down, looking at amount of insulin injected and then adjusting the insulin up or down so that bg levels start to become within target levels.
Ideally your son's bg levels need to be within 4-7mmol before he eats a meal and probably 7-9mmol 2hrs later, then returning back to 4-7mmol again within the next 2-3hrs. Once you've figured out through bg testing the correct carb ratios to use, then things will all start to fall into place and you wont be so baffled. From what you have written... sounds like the 1u to 25g carb ratio is not enough insulin, so if I;ve understood you correctly I think you need to adjust that ratio and use for example 1.5u to 25g carb.
Hope that what I have just said, explains things a bit more..........
