What should the recirculation time for a dialyzer not exceed once set up for treatment?

The recommended recirculation time for a dialyzer should not exceed 2 hours once it has been set up for treatment. This guideline is important for maintaining the integrity and efficacy of the dialysis process. If the recirculation time exceeds this limit, there is an increased risk of compromising the dialyzer's performance, which might lead to inefficient clearance of waste products and toxins from the patient's blood. Additionally, prolonged recirculation can heighten the risk of microbial contamination, potentially impacting patient safety. Thus, adhering to the 2-hour limit ensures optimal functionality of the dialyzer while minimizing risks associated with longer recirculation times.
