摘要：
A peritoneal dialysis system includes a cycler operable with a disposable cassette, the cassette connected to a patient line, the cassette capable of fluid communication with a catheter having access to a patients peritoneal cavity, the cycler configured to: (i) convey dialysis fluid to the peritoneal cavity through the patient line and the catheter during a patient fill phase (ii) allow the dialysis fluid to dwell within the peritoneal cavity during a patient dwell phase (iii) convey dialysis fluid away from the peritoneal cavity through the patient line and the catheter during a patient drain phase and (iv) sense, at first and second sensing locations of the disposable cassette via first and second pressure sensors, an intraperitoneal pressure through the catheter to optimize an amount of fluid conveyed during the patient fill phase, so that the peritoneal cavity is not overpressurized during the patient dwell phase.
