Hemodialysis machines

We tested three conventional single-pass, single-patient hemodialysis machines, from three manufacturers, that can be used in hospital intensive care units, hospital-based dialysis units, freestanding dialysis centers, and patients' homes. All three machines provide adequate and safe performance if users are properly trained and are vigilant while using them. The machines are rated and ranked according to application: all three units are rated Acceptable for hospital and dialysis center use--two are ranked equal and the third is ranked slightly lower because of its overall design; for home use, one machine is rated Acceptable and is preferred, and the other two machines are rated Acceptable-Not Recommended. We also briefly examined another system, described in a separate article in this issue. Also see the Discussion section, where we discuss issues in selecting and using hemodialysis machines, and the articles on dialysate conductivity meters, water treatment for hemodialysis, and the results of our user survey in this issue.
