Abstract

A dialysis method includes: receiving at least one of blood pressure data from a blood pressure monitor or patient weight data from a weight scale at a dialysis machine at least one of (i) before or (ii) after each treatment performed by the dialysis machine; generating ultrafiltration (“UF”) removed data over a treatment performed by the dialysis machine; sending the UF removed data and at least one of the blood pressure data or the patient weight data to a server; determining at least one of a UF trend, a blood pressure trend or a patient weight trend from the UF removed data, the blood pressure data or the patient weight data, respectively; and displaying at least one of the UF trend, the blood pressure trend or the patient weight trend so that a therapy adjustment can be made if necessary.
