Abstract
A dialysis system includes at least one pneumatic valve, a pneumatic pump in fluid communication with the pneumatic valve, a pneumatic line communicating with an inlet and an outlet of the pneumatic pump, a flow restrictor placed in the pneumatic line, and a logic implementer. The logic implementer is programmed to operate the pneumatic valve to either (i) communicate the pneumatic outlet with the pneumatic inlet of the pneumatic pump through the flow restrictor and the pneumatic line, or (ii) communicate the outlet of the pneumatic pump with a component of the dialysis system.
