Yourpump nurse will work out your starting basal from you last several TDD of insulin, and will also work out your lkely correction dose...
Different clinics start with different protocols concerning the basal, a lot will start you off on a flat 24 basal, other will use you bg data to see if they can build a starting profile off.. When I started I kept to the same ratio's for bolusing again some clinci pefer otherwise..
I know that some clinics do like to avoid fasting tests as they haven't always quite moved on from the old theory of the diabetic needs to consume carbs at regular interviews :? Not sure why perhaps we can't be trusted to carry out a fasting test safely
But there really isn't any other effective way than doing a fasting test to find out what the basal is up to, and where to make you adjusments to... believe me if there was I would be using it..
Getting your basal some find it's hard going other find it not so bad, but it very much depends how much matching there really needs to do to match the flutuating deliver of glucose of the liver... And if you don't do fasting tests then you are going to find it extremely difficult and almost impossible to pin down your basal..
Remember though that your last dose of background insulin will take a couple of days to filter out your system, suprising how long it can last when you don't want it to! So give it a couple of days for this to clear before doing any fasting tests...
Also remember the same rule from MDI of changing one thing at a time also applies to insulin pumping, when basal testing concetrate on one basal fasting sector at a time, get this sorted then move onto the next, sometime due to a knock on effect you might have to stop working on one sector, and have a look what happening in another sector and sort though..
Same has with MDI, if you make an adjustment the give it a day or so, to see how it pans out..
Good luck for tomorrow,
A good book to get is Pumping Insulin by John Walsh, it is often referred to as the pumpers bible I've got it and it's worth every penny I spent on it, at the moment it's on offer on Amazon for just over a tenner.. And this is as far as I know the only place you can order it..
