Does dialysis water have higher levels of bacteria?
Results:The more strict cultivation conditions simulate dialysis water environment and have been demonstrated to produce higher levels of bacteria as compared to previous conditions. Although higher levels of bacteria are expected, some testing has shown little difference between the old and new conditions. However, the deviation within AAMI allows for a quicker response time should results be outside acceptable parameters.
What is a dialysis water distribution system?
The distribution system is the piping and valves used to convey the purified water from the water treatment area to the individual dialysis station. Distribution piping is installed in a direct feed or indirect feed style. A direct feed system utilizes the reverse osmosis pump to supply the distribution piping with purified water. An indirect feed system utilizes a storage tank and distribution pump to supply the distribution piping with purified water. Materials that have been used for dialysis water distribution systems include polyvinyl chloride (PVC), natural (non-pigmented) polypropylene, stainless steel and glass. PVC is usually the material of choice for dialysis water distribution systems.
