What pump are you getting? Google the manual for it, most can be found on line and some Manufacturers do an interactive demo on their website so check that out as well,
When sorting out which infusion set to use (each pump will have several different types of infusion sets and cannula lengths) as if you can also take a selection of different ones home with you to try out as well..
Dependant how they arrange your last background jab, if you inject once a day, they often say take half the dose on the night before, or like me a split background I just didn't have my morning jab.. But can take a couple of days for all the residue of the background insulin to wear off, so you sort of get a steady first couple of days and then your control can go slightly screw wiff..
so before making any adjustments to basal give it a day or two, to ensure that you got no old background insulin impacting on your levels.. Get your basal sorted first before really working out your ratio's etc... As if your basal is out all your other calculations will be out as well..
Not sure how your team will tell you to do the basal testing, but night-time is probably to the best one to get out the way, I'm the firm believer the easiest and quickest way of getting basal sorted is fasting testing, every hour.. If you told just test at 3am then you won't have a clue what your BG's are doing before or after this, so adjustment end up a stab in the dark!
Also I suggest you invest in a book called 'Pumping Insulin' by John Walsh it's the pumpers bible, and it explains how to set up a good fasting tests, so your BG isn't being impacted on slow carbs and/or bolus insulin still impacting on the BG..
Change one thing at a time, too many changes means that you won't know what parts did or didn't work and you get in a right old pickle very quickly..
Good luck with it all..
Going on the pump was the best thing I every did and like you I use very little insulin, to give you some idea of my usage my adv TDD is 17 units and my correction factor is 1U=7mmol/l bg drop :shock:
