Abstract: A test method determines at least one status parameter of an individual undergoing peritoneal dialysis. The status parameter(s) may include a transport property of the peritoneum, a tonicity, or a residual volume. The test method includes receiving first data indicative of a flow rate as a function of time of a treatment fluid into and out of a peritoneal cavity during a test procedure, and second data comprising measured data samples representing a concentration of one or more solutes in the treatment fluid at time points during the test procedure. The test method also includes computing, based on the first data and by use of a transport model for a peritoneal membrane, estimated data samples representing the concentration of the one or more solutes in the treatment fluid at the time points and determining the status parameter(s) as a function of the measured data samples and the estimated data samples.

Abstract: A control device performs a method to generate control signals for a dialysis machine, which is configured to perform peritoneal dialysis, PD, treatment comprising one or more fluid exchange cycles in relation to a peritoneal cavity of a patient, to cause a transport of fluid and solutes through its peritoneal membrane. The method comprises: obtaining a target value of a treatment parameter for the PD treatment, obtaining a transport property of the peritoneal membrane, and configuring a transport model by use of the at least one transport property. The transport model defines the transport of fluid and solutes through the peritoneal membrane as a function of control parameters for the PD treatment. The method further comprises: evaluating the transport model to determine set values of the control parameters to achieve the target value, and generating the control signals in correspondence with the set values.
