Patent ID: 8323231

Claim:
A peritoneal dialysis system comprising: a first pump actuator; a second pump actuator; first and second diaphragm pump chambers operable with the first and second pump actuators, respectively, each first and second pump chamber including a dialysis fluid compartment for receiving a dialysis fluid to be delivered to a patient line; a pressure sensor located at a conduit upstream or downstream from one of the first and second pump chambers, the conduit in communication with the dialysis fluid compartment of the first or second pump chamber, the pressure sensor sensing a pressure of a dialysis fluid in the conduit, the patient line in fluid communication with the dialysis fluid compartment via the conduit, the conduit opened and closed via a dialysis fluid valve; and wherein the system is configured to receive a signal from the pressure sensor and use the signal to modify a peritoneal dialysis treatment from a planned peritoneal dialysis treatment performed by the system to avoid an alarm condition.
