Final answer:
Indications for dialysis or apheresis catheters include renal failure, need for frequent or prolonged treatments, and long-term administration of medication or fluids.
Step-by-step explanation:
Indications for dialysis or apheresis catheters include:
- Renal failure: When a person's kidneys fail to remove waste products and excess water from the blood, hemodialysis or apheresis may be necessary to artificially filter them out.
- Need for frequent or prolonged treatments: Patients who require frequent or prolonged dialysis sessions may opt for catheters to provide easier access for the procedure.
- Long-term administration of medication or fluids: Venous catheters may be used for patients who require long-term administration of medication or fluids.
