Testing of a Medical Fluid Treatment System

A method for detecting a failure in a system for providing a medical treatment to a patient, the system including a fluid pathway in removable fluidic communication with the patient, a pump, a memory device, and a sensor for measuring a pressure in the fluid pathway, the pump, the memory, and the sensor being operatively connected to an electronic processor, the pump being configured to move a fluid through the fluid pathway and the system being configured to infuse or remove the fluid to or from the patient via the fluid pathway, the method comprising the steps of:

• performing a test to detect an operational failure of the system, the test including,
• actuating the pump,
• measuring a pressure in the fluidic pathway by the sensor,
• determining a test result based on the measured pressure,
• recording data of the test result in the memory device,
• monitoring a trend of the data of the recorded test result in the memory device, and
• determining the operational failure of the system based on the data of the recorded test result.

• receive a pressure in the fluid pathway measured by the sensor,
• determine a test result based on the measured pressure,
• record data of the test result in the memory device,
• monitor a trend of the data of the recorded test result in the memory device, and
• determine an operational failure of the system based on the data of the recorded test result.
