1. An apparatus for performing peritoneal dialysis comprising:
- a housing;
a peritoneal dialysis supply bag supported by the housing, such that in use the peritoneal dialysis supply bag is located elevationally above a patient;
a first valve for controlling gravity flow of fresh peritoneal dialysis fluid from the peritoneal dialysis supply bag to the patient;
a second valve for controlling gravity flow of used peritoneal dialysis fluid from the patient to a drain, wherein the drain in use is located elevationally below the patient;
a first pressure sensor positioned and arranged with respect to the gravity flow of fresh peritoneal dialysis fluid to provide a first reading used to evaluate a first gravity head pressure;
a second pressure sensor positioned and arranged with respect to the gravity flow of used peritoneal dialysis fluid to provide a second reading used to evaluate a second gravity head pressure; and
a controller configured to establish the first and second gravity head pressures due to a location of the peritoneal dialysis supply bag and a location of the drain using the first and second readings.

16. A method for performing peritoneal dialysis comprising:
-
enabling gravity flow of fresh peritoneal dialysis fluid to a patient; enabling gravity flow of used peritoneal dialysis fluid from the patient; sensing a first pressure of the fresh peritoneal dialysis fluid prior to flowing to the patient and a second pressure of the used peritoneal dialysis fluid prior to flowing from the patient; and programming a controller to evaluate (i) a first gravity head pressure from the first sensed pressure prior to a flow of the fresh peritoneal dialysis fluid into a peritoneal cavity of the patient and (ii) a second gravity head pressure from the second sensed pressure prior to a flow of the used peritoneal dialysis fluid from the patient'"'"'s peritoneal cavity. - View Dependent Claims (17)
