WHile it is true this method isn't as quick as treating it...it does
work effectively. The reason that you adjust basal rates 1 1/2 to 2
hours before you need it is because it takes almost an hour before you
actually start getting any EXTRA insulin (or less insulin). Why?
Well, let's say that your basal rate is .5 u/h, and you need to
increase it to .7 u/h. That is only an extra .2 u/h. WHen you spread
that out over an hour, that works out to an extra .03 units every 10
minutes. Most pumps can't even handle that resolution of delivery, and
the Minimed pumps use a resolution of .1 units. So, the FIRST time
that you get that extra first .1 unit is about 30 minutes after the
time you set the adjustment (on average).
However, suspending (or better, using a temporary basal rate of 0)
takes effect immediately. The only delay is the delay that it takes
for the insulin to start (or, in this case NOT start working) which is
on the order to 10-20 minutes. And, in the case of Humalog, which has
its peak sooner than Novolog (Novolog is more an "even" curve), you
would see even faster results.
I have used a temporary basal rate of 0 to treat some mild lows quite
successfully. BG levels start to return to normal within 30 minutes
usually, which is fine for mild lows. Novolog users MAY see a slightly
longer delay in the rise, but probably not by much.
