What check is performed weekly and before the first treatment after disinfection?

The weekly check performed on residual bleach is critical in ensuring that the disinfection process for hemodialysis machines is effective. Residual bleach testing is typically done to confirm that any remaining disinfectant is at safe and effective levels before the machine is used for patient treatments. Measuring residual bleach helps verify that the disinfection process has not introduced harmful levels of bleach that could affect patient safety during dialysis.

While chlorine levels and temperature calibration are also important checks in the maintenance of dialysis equipment, they do not specifically correlate to the immediate concerns related to disinfection residues. Flow rate measurements are crucial for ensuring that the dialysis procedure operates efficiently but do not directly relate to the disinfection status of the machine. Therefore, testing for residual bleach specifically addresses the need for safety and effectiveness prior to patient treatment.
