The present system and method in one embodiment limit a maximum instantaneous peritoneal volume to a comfortable level, while allowing the dialysis machine to advance to fill a prescribed volume whenever the drain ends after a minimum drain percentage has been attained. If a low drain condition occurs, the nominal fill volume is lowered and a therapy cycle is added, so that a prescribed total amount of fresh therapy fluid is used during therapy, maximizing therapeutic benefit. An allowable residual volume at the end of an incomplete drain is increased, thereby lowering the probability of a subsequent low drain condition. |

1. A system for performing a peritoneal dialysis therapy comprising:
at least one dialysis fluid pump; and a control unit operable with the at least one dialysis fluid pump to perform a plurality of peritoneal dialysis cycles, the cycles including a fill phase, a dwell phase and a drain phase, the control unit configured, upon a user selection to perform a continuous cycling peritoneal dialysis (“CCPD”) therapy, to: (i) avoid a maximum peritoneal volume being exceeded after any of the dwell phases of the plurality of patient cycles, (ii) ensure that a prescribed total sum of dialysis fluid volume of the fill phases is delivered to the patient, and (iii) determine if (1) a residual volume left in the patient after one of the drain phases based on a minimum drain percentage will cause the maximum peritoneal volume in (i) to be exceeded during a next cycle, and if the determination in (1) is yes, determine if (2) a threshold minimum drain percentage after the one of the drain phases cannot be achieved,
if the determination in (2) is yes, activate an alarm, andif the determination in (2) is no, reduce an amount of dialysis fluid volume of the fill phase of the next cycle and add an extra cycle to the peritoneal dialysis therapy so that (ii) is satisfied. |
