Abstract:
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 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 amount of ultrafiltrate (“UF”) removed from the patient for the first dwell time; (iii) cause the at least one pump to pump fresh dialysate to the patient and drain spent dialysate from the patient after a second and different dwell time; (iv) determine, as a portion of the second spent dialysate, a second amount of UF removed from the patient for the second, different dwell time; (v) fit a curve to at least the first UF removal amount and the second UF removal amount; and (vi) use the curve to determine an optimal dwell time or dwell time range for the patient.
