Hi
Sorry to hear that you are running low and then high's. I for one also know how extremely frustrating this is...
If I have unexplained high's the first thing I do is to change the set BEFORE I do a correction bolus.
I write down everything reagrding high's regards what I have ate, when I have changed medication..even where I have put the sets in my body....
If my levels go high, and I know it isn't down to me then I also do a reprime with a large amount of banging the pump to get the bubbles out. I know well and truly nowadays when my high's are down to me or the pump.
For example I went high during the night and woke up to levels of 14 this morning. When I looked at my rapid d set, all around the top sticky white stuff is was blood. THerefor my high was down to the set. This is the 2nd time I have had this with the rapid d sets, that they do not hurt but I have high levels and find blood leaking around the top of the rigid set bit. I don't know why this is, and I personally find it very, very frustrating. And yes, I do reflect that at least on MDI I knew the insulin was definitely in me, rather than waking up to high levels and finding the set has problems.
I find if I have high levels which aren't down to me, the best thing to do is a good bang of the pump and prime out any bubbles that may have accumulated in the lueur connector, and to definitely change the set.
I also write down the batch numbers of new boxes of sets and tubes, as I complained to my DSN about the flexilink plus's causing me problems and to Roche, and 4 months later they were recalled.
I still don't 100% trust the equipment to be quite honest, as I am yet to have a high that has been down to me!!!!
