A system is disclosed for the automated collection of dialysis and physiological data. An example system includes a dialysis machine configured to generate dialysis data and a wireless peripheral device configured to generate physiological data. The system also includes a personal digital device including an application configured to communicatively couple to the dialysis machine. The application is further configured to detect being within a wireless range of the wireless peripheral device, pair with the wireless peripheral device, receive the physiological data from the wireless peripheral device, and transmit the received physiological data to the dialysis machine. The dialysis machine is configured to store the received physiological data in conjunction with the dialysis data.

System for automated collection of dialysis data

A method for performing a peritoneal dialysis therapy includes performing a plurality of peritoneal dialysis cycles for a patient and tracking an amount of dialysis fluid provided by at least one dialysis fluid pump during the plurality of peritoneal dialysis cycles. The method also includes determining an amount of ultrafiltrate ('UF') removed from the patient based on the amount of dialysis fluid provided by the at least one dialysis fluid pump. The method further includes updating a UF trend using previous amounts of UF removed from the patient and the amount of UF removed from the patient during the most recent dialysis treatment and generating an alert if the UF trend changes by more than a preset percentage.

System and method for preparing peritoneal dialysis fluid at the time of use

A system and method are disclosed for the automated collection of dialysis data. An example method includes receiving and aggregating dialysis data comprising a fill volume amount and a drain volume amount for at least one continuous ambulatory peritoneal dialysis ('CAPD') cycle. The method also includes calculating an amount of ultrafiltration removed for each CAPD cycle by subtracting the fill volume amount from the drain volume amount for the respective CAPD cycle, and storing ultrafiltration data that is indicative of the amount of ultrafiltration removed as part of the aggregated dialysis data. The method further includes determining or receiving an indication that a dialysis machine is connected. After the dialysis machine is connected, the method includes transmitting the aggregated dialysis data to the dialysis machine to enable the aggregated dialysis data to be combined with additional dialysis data generated by the dialysis machine for determining total dialysis data.
