1. A peritoneal dialysis system comprising:
- a housing;
at least one pump carried by the housing and configured to fill a patient with fresh dialysate and drain spent dialysate from the patient; and
a logic implementer configured in an ultrafiltration (“
UF”
) evaluation sequence to;
(i) cause the at least one pump to pump fresh dialysate to the patient and drain spent dialysate from the patient after a first dwell time;
(ii) determine, as a portion of the first spent dialysate, a first an amount of UF removed from the patient for the first dwell time;
(iii) cause the at least one pump to fresh dialysate to the patient and drain spent dialysate from the patient after a second and different dwell time, and(iv) as a portion of the second spent dialysate, a second amount of UF removed from the patient for the second, different dwell time.

Abstract
An ultrafiltration (“UF”) evaluation method includes: (i) determining an amount of UF removed from a patient over a first dwell time; (ii) determine an amount of UF removed from the patient over a second, different dwell time; (iii) determining an amount of UF removed from the patient over a third, different dwell time; and (iv) fitting a curve to the UF removal amounts for the first, second and third dwell time. A peritoneal dialysis therapy generation method using the curve determined according to the “UF” evaluation method to generate at least one peritoneal dialysis therapy regimen.
