Drain and fill logic for automated peritoneal dialysis

摘要

A system and method for automatically adjusting a Continuous Cycling Peritoneal Dialysis (“CCPD”) therapy to minimize the potential for excess intra-peritoneal volume. The adjustments are made at the end of the drain, just prior to the next fill. The adjustments short the next fill, if necessary, to limit the intra-peritoneal volume, add a cycle, if necessary, to use all of the available dialysis solution and will average the remaining dwell time to maximize the therapeutic benefit of the therapy in the allotted time. In another embodiment, a tidal therapy using trended patient UF data is provided.

主权项

1. An automated peritoneal dialysis method comprising:
pumping dialysis fluid to and from a dialysis machine and a patient over a multi-cycle dialysis therapy including a plurality of patient fills, dwells, and drains; providing a logic implementer with the dialysis machine to (i) calculate cumulative ultrafiltration during the multi-cycle dialysis therapy, and (ii) reduce a prescribed volume for at least one of the plurality of patient fills through controlling the pumping of the dialysis fluid to and from the dialysis machine when an amount of a prior incomplete one of the plurality of drains causes the cumulative ultrafiltration at an end of the prior incomplete drain to exceed a negative ultrafiltration limit.
