A method of performing closed-loop dialysis treatment during hemodialysis is provided. The method involves determining an initial ultrafiltration rate and setting an ultrafiltration pump of a dialysis system to the determined ultrafiltration rate. A series of measurements and calculations are made to ensure that a rate of change of blood volume during treatment follows a specified profile. A threshold may be used to keep the rate of change of blood volume tracking the profile. Patient fluid dynamics may be measured in real-time and used to determine the ultrafiltration pump rate.

A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a microphone and a component that provide voice recognition capabilities to the machine. For example, in some implementations, the component is configured to identify and/or authenticate voice commands that are issued by a user. The voice command may cause the dialysis machine to carry out a dialysis function. Alternatively, the voice command may cause a user interface of the dialysis machine (e.g., a display, such as a touchscreen display) to be adjusted. A dialysis machine can also include a speaker for providing spoken information to a user. For example, in some implementations, the speaker can provide spoken instructions to assist the user in machine set-up, calibration, and/or operation. Such spoken instructions can be particularly useful in a home dialysis setting. In some implementations, the speaker can provide spoken alarms that are related to alarm conditions.
