Some common malfunctions of<unk> s include clotting, infection, and kinking. One of the most common errors of tunnel hemodialysis<unk>  insertions is failure to locate the arterial limb of the<unk>  medially and the venous limb laterally. This must be done, because most<unk> s have a memory in the plastic, which will cause the<unk>  to try to resume its natural straight form. If the arterial limb is placed laterally, this will cause the arterial inlet to float up against the vein wall, or even up against the rim of the inlet of the atrium. This has the same effect as a vacuum cleaner hose sucking up against curtains. This results in poor blood flows, and can force the<unk>  staff to reverse flow, using the venous limb of the<unk>  as the arterial. This will result in more inefficient<unk> , as there will be admixing of blood from the<unk>  (cleaning the same blood, over again). A<unk>  must have infusion of 30cc or greater to keep the line open. Intravenous fluids at 30ml per hour should be hung if being used for infusion.
