Lipopolysaccharide components of bacterial cell walls that cause pyrogenic reactions; their levels in dialysis water must be strictly controlled per AAMI/ISO standards.
Endotoxins are released when Gram-negative bacteria die and are a major contaminant risk in dialysis water and dialysate. The maximum allowable endotoxin level in standard dialysis water is 0.25 EU/mL (AAMI RD52/ISO 23500), with an action level of 50% (0.125 EU/mL) triggering corrective action. For ultrapure dialysate used in HDF, the limit is <0.03 EU/mL. Elevated endotoxin causes pyrogenic reactions (fever, chills, hypotension) and chronic inflammation. Monitoring requires monthly endotoxin testing with documented corrective action logs — see the water treatment monitoring log.
The purification system that produces ultrapure water for dialysate preparation, critical for patient safety during hemodialysis.
The water purification system using reverse osmosis membranes to produce ultrapure water required for dialysate preparation in hemodialysis.
The specially formulated solution used in dialysis that draws waste products and excess electrolytes from the blood across the dialyzer membrane.
A medical procedure that filters waste products, excess fluids, and toxins from the blood using a dialysis machine when the kidneys can no longer perform this function adequately.
