Key Peritoneal Dialysis Components & Specifications 

• Dialysate Solution:
  • Osmotic Agents: Typically glucose (dextrose) at concentrations of 1.5%, 2.3%, or 4.25% to remove fluid. Alternative agents include icodextrin (for long, 8-12+ hour dwells) or amino acids.
  • Buffer Systems: Lactate-buffered (conventional) or biocompatible bicarbonate/lactate-buffered, with a neutral pH (around 7.4) preferred to minimize membrane damage.
  • Electrolytes: Sodium (132–134 mEq/L), Calcium (

• Treatment Modalities (Prescription Specs):
  • CAPD (Continuous Ambulatory Peritoneal Dialysis): Usually 4 exchanges/day, 2–3 liters per exchange, with 4–8 hour dwell times.
  • APD (Automated Peritoneal Dialysis): Typically 7–10 hours overnight, 3–10 cycles, with 1.5–3.0 L volumes.
• Catheter Specifications: A soft, flexible silicone or polyurethane tube (e.g., Tenckhoff catheter) is placed into the lower abdomen via surgical, laparoscopic, or percutaneous technique.
• System Requirements: Equipment must conform to standards for safety (e.g., IEC 60601-2-39).
• Monitoring (Adequacy): The total weekly
