1. A method for performing dialysis treatments comprising:
performing, using a logic implementer of a dialysis machine operable with at least one dialysis fluid pump, a present dialysis treatment related to a peritoneal dialysis therapy prescription for a patient, the present dialysis treatment having a plurality of peritoneal dialysis cycles, the cycles including a fill phase, a dwell phase, and a drain phase, wherein the peritoneal dialysis therapy prescription specifies parameters for the present dialysis treatment including at least
(a) a total prescribed fresh dialysis fluid fill volume to be delivered over the plurality of peritoneal dialysis cycles,
(b) an expected amount of ultrafiltrate (“UF”) to be removed per peritoneal dialysis cycle or per the present dialysis treatment,
(c) a maximum allowable peritoneal volume value, and
(d) a dextrose level of a dialysis fluid;
transmitting, from the logic implementer to a network, an amount of dialysis fluid provided by the at least one dialysis fluid pump to a peritoneal cavity of the patient during the present dialysis treatment;
receiving, in a server from the network, the amount of dialysis fluid provided during the present dialysis treatment;
determining, via the server, an amount of UF removed from the patient based on the amount of dialysis fluid provided by the at least one dialysis fluid pump;
determining, via the server as an initial drain volume, how much dialysis fluid resides in the patient's peritoneal cavity at a start of a next dialysis treatment based on at least one of (a) to (d), the amount of dialysis fluid provided during the plurality of peritoneal dialysis cycles, and the amount of UF removed;
updating, via the server, a UF trend using previous amounts of UF removed from the patient during previous dialysis treatments and the amount of UF removed from the patient during the present dialysis treatment;
updating, via the server, an initial drain volume trend using previous initial drain volumes during the previous dialysis treatments and the initial drain volume for the start of the next dialysis treatment;
causing, via the server, the UF trend and the initial drain volume trend to be displayed for clinician review;
receiving, in the server, data indicative of an initial drain flow for the next dialysis treatment;
generating, via the server, an alert when it is determined from the received data that a low drain flow or a drain flow stoppage could occur before the initial drain volume is recovered for the start of the next dialysis treatment;
causing, via the server, the alert to be displayed;
receiving, in the server, a new peritoneal dialysis therapy prescription with at least one of (a) to (d) changed;
transmitting, from the server to the logic implementer, a message indicative of the new peritoneal dialysis therapy prescription; and
performing, using the logic implementer and the at least one dialysis fluid pump of the dialysis machine, the next dialysis treatment according to the new peritoneal dialysis therapy prescription by controlling at least a plurality of peritoneal dialysis cycles specified by the new peritoneal dialysis therapy prescription, a total treatment duration specified by the new peritoneal dialysis therapy prescription, and a total prescribed fresh dialysis fluid fill volume specified by the new peritoneal dialysis therapy prescription.
