Abstract

Systems for performing peritoneal dialysis having an improved user interface functions and monitoring capabilities. In one respect, the systems discriminate between alarm conditions that require user intervention to correct and alarm conditions that reflect conditions that are anomalies but typically correct themselves with minimum or no user intervention. In another respect, the systems identify occluded liquid flow paths and discriminate whether the flow path is associated with a liquid source or a liquid destination.
