We met with an endocrinologist last month and he agreed that our daughter should start using a pump as soon as we can. So we took the required pump assessment class. The formula they use as a starting point to find basal is: ((long acting units)*(0.75))/24. In my daughters case, that would be ((0.5)*(0.75))/24 = 0.016 That would below the capabilities of any pump on the market. So, my next thought is to use the pump for corrections and meal covering. The long acting would still be used at 0.5/units in the morning. Has anyone here had to do some combination like that?
