Would you agree that of the many dialysis modalities in place, all are now technologically satisfied(do not require technical creativity) and that the only concerns to the technologist to date are; controlling the level of bacteria and endotoxin in the dialysate, assuring the quality of the dialysate, evaluate new equipment, maintain equipment and control costs (maybe also give a few inservices of the principles of dialysis and how to operate and trouble shoot the equipment)? Is there anything else that I may have missed, I may not be old but I can still miss a point or two?
