Dialysis system having adaptive prescription management

A peritoneal dialysis system comprising:

• at least one pump;
• a memory device configured to store:
• therapy prescriptions including:
• a high ultrafiltration (“UF”) therapy prescription for removing a first amount of ultrafiltrate from a patient, and
• a standard UF therapy prescription for removing a second amount of ultrafiltrate from the patient, the second amount of ultrafiltrate being less than the first amount of ultrafiltrate, or a low UF therapy prescription for removing a third amount of ultrafiltrate from the patient, the third amount of ultrafiltrate being less than the second amount of ultrafiltrate;
• and
• a logic implementer communicatively coupled to the memory device and configured to:
• receive UF removed data related to performing the high UF therapy prescription or the low UF therapy prescription or the standard UF therapy prescription for a peritoneal dialysis treatment,
• use the UF removed data to form or update a moving average UF removed trend,
• determine a trending range around the moving average UF removed trend,
• determine a lower UF removed limit from the trending range,
• compare the moving average UF removed trend to the lower UF removed limit from the trending range,
• when the moving average UF removed trend is below the lower UF removed limit, provide a recommendation, via a user interface, that the high UF therapy prescription should be selected for a next peritoneal dialysis treatment,
• receive a selection of the high UF therapy prescription for the next peritoneal dialysis treatment, and
• control the at least one pump based on the high UF therapy prescription to perform the next peritoneal dialysis treatment.

A peritoneal dialysis system comprising:

• at least one pump;
• a memory device configured to store:
• therapy prescriptions including:
• a first ultrafiltration (“UF”) therapy prescription for removing ultrafiltrate from a patient, and
• a second UF therapy prescription for removing less ultrafiltrate from the patient compared to the first UF therapy prescription;
• and
• a logic implementer communicatively coupled to the memory device and configured to:
• receive UF removed data related to performing peritoneal dialysis treatments,
• use the UF removed data to form or update a moving average UF removed trend,
• compare the moving average UF removed trend to an expected UF removal trend or an expected UF removal minimum value,
• when the moving average UF removed trend is below the expected UF removal trend or the expected UF removal minimum value, provide a recommendation, via a user interface, that the first UF therapy prescription should be selected for a next peritoneal dialysis treatment,
• receive a selection of the first UF therapy prescription for the next peritoneal dialysis treatment, and
• control the at least one pump based on the first UF therapy prescription to perform the next peritoneal dialysis treatment.
