What is the maximum time allowed for recirculation of blood-tinged saline during interruption?

• A. 30 minutes
• B. 15 minutes
• C. 10 minutes
• D. 60 minutes

Answer: (A)

During a dialysis interruption, you may flush the circuit with saline to keep the lines clear and prevent clotting. If some blood-tinged saline starts recirculating, it means blood from the patient is looping back into the saline pathway rather than moving through the circuit as intended. This situation needs a safety limit because the longer the recirculation continues, the higher the risk of clot formation in the circuit and potential excess dilution or loss of blood, plus the catheter or fistula may not be functioning properly. The maximum time allowed for this recirculation is 30 minutes. This window gives you enough time to check and correct issues such as catheter position, line connections, or flow problems and to restart dialysis promptly with the circuit functioning correctly. If recirculation persists beyond 30 minutes, take corrective action or escalate rather than letting it continue.
