Fistula Condition Monitoring System by the Noise Changes Dynamics

The paper presents an automated system for collecting and processing data for diagnosing the condition of an arteriovenous fistula. In the fistula, due to increased blood flow, characteristic noises and vibrations of the vessel walls occur. Using the data acquisition device, the acoustic noise of the arteriovenous fistula is recorded. The system processes and analyzes the measured data, evaluates the main indicators of the fistula condition. Changing the main indicators allows you to evaluate the dynamics of changes in the fistula condition. The developed system can be used for remote, long-term and continuous diagnostics of blood vessels in patients on hemodialysis.
