You can go to this website and get an unbiased look at all the different dialysis companies and what they are doing to improve dialysis treatments. It is put out by AAMI (Association for the Advancement of Medical Instrumentation). I found lots of interesting info about new stuff my company has that I didn't even know existed. It even has a search feature to look up older info than their current publication. Try looking up your dialysis company of machine manufacturer to see what info you can find. The site address is as follows.
