Abstract
A peritoneal dialysis (“PD”) system includes a PD fluid pump, a disinfection loop including the PD fluid pump, the disinfection loop including PD fluid used for disinfecting the disinfection loop, and an acid solution source positioned and arranged to supply an acid solution to the disinfection loop during disinfection using the PD fluid. The disinfection loop includes an airtrap and a pressure sensor positioned and arranged to sense PD fluid pressure during disinfection, the pressure sensor outputting to a control unit, the control unit configured to open at least one gas valve located along at least one gas line leading to an upper portion of the airtrap when the PD fluid pressure reaches or exceeds a threshold PD fluid pressure due to gas formation caused by mixing the acid solution with the PD fluid.
