Len, Sure...turn a perfectly reasonable answer into a more difficult question! ;-) I can't answer absolutely, since, (as you know) it is a YMMV thing. BUT, in general, you have to look at it this way: First, you need to know how much unused insulin is still in your system after you gave your correction. Once you have a decent unused insulin rule, you can then test, say, 2 hours later and see if your BG level has dropped according to how much insulin has been used. In your example, if apply the "standard" unused insulin rule of 30% used up every hour, then after 2 hours, if you gave 4 units, then 60%, or 2.4 units, have been used up. 2.4 units SHOULD have lowered your BG level by 48 points, or 152. When you test your BG level, and you find, however, that it is actually 190, then you know that the insulin you gave won't be enough. At this point, you have to re-calculate your insulin requirements for 190 (which would be 3.5 units) and subtract out unused insulin (which would be 1.6 units). This means you can "safely" give an additional correction of 1.9 units. A lot of calculations, but for me, I just use Logbook DM to handle all the work for me, so for me the entire correction only takes seconds to do. The biggest key is coming up with a fairly accurate unused insulin rule for yourself. For ME, I use the following unused insulin rule that works VERY well: I assume that humalog will last a TOTAL of 3.5 hours. I also calculate that 85% of the insulin will be used up in the first 1.75 hours, and the remaining 15% will be used up in the last 1.75 hours. (Again, Logbook DM handles this calculation for me, so it isn't difficult.) Hope this helps!!! :-) (Once again, YMMV.)
