1. A method of performing peritoneal dialysis, the method comprising:
- receiving input data regarding a prescribed dextrose concentration and a dextrose concentration of each of a plurality of different commercially available, pre-packaged dialysates, wherein the dextrose concentrations of the pre-packaged dialysates differ from one another;
disposing a first dialysate having a first concentration of dextrose in an abdominal cavity of a patient for a first period of time, and then removing the first dialysate from the abdominal cavity of the patient after the first period of time;
after removing the first dialysate from the abdominal cavity of the patient, disposing a second dialysate having a second concentration of dextrose in the abdominal cavity of the patient for a second period of time, and then removing the second dialysate from the abdominal cavity of the patient after the second period of time, the second concentration of dextrose being lower than the first concentration of dextrose; and
after removing the second dialysate from the abdominal cavity of the patient, disposing a third dialysate having a third concentration of dextrose in the abdominal cavity of the patient for a third period of time, and then removing the third dialysate from the abdominal cavity of the patient after the third period of time, the third concentration of dextrose being lower than the second concentration of dextrose,wherein the first, second, and third dextrose concentrations are determined based on the input data, and wherein disposing the first, second, and third dialysates in the abdominal cavity comprises delivering at least a portion of at least one of the pre-packaged dialysates to the abdominal cavity, and at least one of the first, second, and third dialysates is a mixture of the plurality of pre-packaged dialysates.

Abstract
Peritoneal dialysis systems and related methods are disclosed. The methods can include combining a first solution having a first concentration of a solute with a second solution having a second concentration of the solute to form a custom dialysate, e.g., according to a specific prescription for a patient.

24. A method of performing peritoneal dialysis treatment, the method comprising:
-
combining a dialysate concentrate having a dextrose concentration of ten percent to 30 percent, a calcium concentration of about 5.9 mEq/L to about 70 mEq/L, and a magnesium concentration of about 1.2 mEq/L to about 30 mEq/L with a diluent to form a first dialysate, wherein the diluent is reverse osmosis water or saline; disposing the first dialysate in an abdominal cavity of a patient for a first period of time; and removing the first dialysate from the abdominal cavity of the patient after the first period of time. - View Dependent Claims (25, 26, 27, 28, 29)

30. A peritoneal dialysis system, comprising:
-
a first container containing a dialysate concentrate having a dextrose concentration of ten percent to 30 percent, a calcium concentration of about 5.9 mEq/L to about 70 mEq/L, and a magnesium concentration of about 1.2 mEq/L to about 30 mEq/L; a second container containing a diluent, wherein the diluent is reverse osmosis water or saline; a mixing container in fluid communication with the first and second containers; and a pump configured to pump metered amounts of the dialysate concentrate and the diluent to the mixing container to form a dialysate. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
