The ISF on my pump was initially setup at 1:3 when I first started on the pump. But last week the nurse wasn't happy with the speed at which the correction boluses were taking effect so did a recalculation of the ISF for me. I'm now finding that the correction boluses are sending me low so am just going to split the difference between the 1:3 I was on before, the 1:2 that she changed me to and set it up as 1:2.5 and see how that goes.
They seemed to use an incredibly crude method of figuring it out though, just dividing the average total daily dose of insulin into 100. That doesn't sound a particularly good way of figuring out how sensitive you are to insulin when it is not taking into account other factors, such as how much your eating or exercising.
All I can find online about how to figure out the sensitivity is just similar calculations, although using the US units mostly. Can anyone explain the thinking behind such a basic method of figuring it out? Am I missing something obvious in how they come up with the numbers?
