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 a carbon dioxide (CO2), source positioned and arranged to supply CO2 to the disinfection loop to inhibit and/or remove the production of calcium carbonate (CaCO3) during a disinfection sequence. The PD system includes a control unit configured to open a valve to allow CO2 to be supplied, wherein the control unit may use a lookup table or algorithm to determine the desired pressure or pressure increase.
