After completing this module, the learner will be able to:
1. Identify the purpose and characteristics of dialyzers.
2. Describe the purpose and chemical composition of dialysate.
3. Describe dialysate preparation and the three monitoring functions of the dialysate delivery subsystem.
4. Describe the extracorporeal blood circuit functions anti monitoring systems.
Introduction
• A dialyzer lets the patient's blood interact with dialysate through a semipermeable membrane.
• Dialysate is a blend of treated water and chemicals; it removes wastes and fluid, and balances electrolytes.
• A delivery system supplies fresh dialysate and removes used dialysate.
• Modem high-tech delivery systems include a blood pump, an ultrafiltration pump, a dialysate conductivity monitor, alarms, and pressure gauges.
• Better membranes, safety monitors, and the use of computers have made dialysis safer.
• These advances allow today's staff to turn more of their time to patients. .
• Trained staff who know dialysis principles, equipment, and procedures are the most vital monitors of patient safely.
