Abstract

An example dialysis system includes a dialysis machine and a receiver coded with at least one of an address or a personal identification number (“PIN”). The dialysis machine is configured to perform a prescribed dialysis treatment on a patient, generate ultrafiltration (“UF”) removed data over the prescribed dialysis treatment performed by the dialysis machine, and transmit the UF removed data. The example receiver is configured to receive sensor data from a sensor attached to the patient. The at least one coded address or PIN ensures that the sensor data is received by the receiver as opposed to another receiver.

5. The dialysis system of claim 3, wherein the network is connected to a server located remotely from the dialysis machine and separate from the dialysis system, and wherein at least one of the receiver or the dialysis machine transmits at least one of the UF removed data and the sensor data to the server via the network.

6. The dialysis system of claim 1, wherein the receiver is provided by the dialysis machine and communicatively coupled to a processor of the dialysis machine.
