Abstract
A method of pneumatically operating a dialysis system includes (i) pumping air in a first valve state from a pneumatic pump to operate a component of the dialysis system, and (ii) recirculating air in a second valve state by pumping air from an outlet of the pneumatic pump to an inlet of the pneumatic pump to minimize at least one of a noise pitch or noise amplitude when switching from the second valve state to the first valve state.
