Machine Setup According to Prescription
Key Takeaways
- Machine settings must match the dialysis prescription and facility policy before treatment starts.
- Common setup checks include dialyzer, bath, blood flow, dialysate flow, treatment time, UF goal, temperature, anticoagulation, and alarms.
- Independent checks and required documentation help catch wrong bath, wrong dialyzer, wrong patient, and wrong treatment setting errors.
- Unclear, missing, or conflicting orders require escalation before initiating treatment.
Turning the Prescription Into a Safe Setup
The dialysis prescription controls what the machine should deliver. The technician may set the machine according to policy, but should not invent or independently change the prescription. If any order is missing, unclear, expired, or inconsistent with the patient or supplies, stop and ask the appropriate licensed staff.
Common prescription elements include patient identity, dialyzer, dialysate bath, sodium, bicarbonate, potassium, calcium, temperature, dialysate flow, blood flow, treatment time, target weight, ultrafiltration goal, anticoagulation, and special instructions. Local forms and electronic systems may use different layouts.
Patient identification is part of setup. The right prescription must be matched to the right patient using required identifiers. A chair number, routine schedule, or memory is not enough when connecting a patient to a machine that can remove fluid and alter electrolytes.
The dialyzer and bloodline set must match policy and prescription. Check packaging, expiration date, sterility indicators if used, dialyzer type, correct line routing, priming, air removal, secure connections, and alarm readiness. Do not use supplies that are damaged, expired, contaminated, or questionable.
UF setup requires careful calculation and verification. The prescribed goal may include expected fluid removal plus rinseback or prime volume depending on facility procedure. A large or unusual UF goal, wrong pre-weight, or mismatch with target weight should be reported before treatment begins.
Before initiation, required machine self-tests, alarm tests, conductivity and pH checks, temperature verification, and documentation must be complete. If the machine fails testing, gives unresolved alarms, or cannot pass required checks, remove it from service according to policy and notify the correct staff.
Setup errors are adverse events or near misses when they could affect treatment. Document facts such as wrong bath discovered before start, dialyzer changed, machine failed test, setup repeated, or RN notified. Do not document that treatment was ready until required checks are truly complete.
