LONDON: Researchers have developed a gadget with the help of an artificial intelligence (AI) system. The goal of the device is to maximise the amount of blood that flows through patients’ veins during dialysis treatments.
Researchers, including those from Imperial College London in the United Kingdom, used computer modeling techniques to model how unsteady currents in blood flow in the veins of patients undergoing dialysis. These techniques are typically employed to simulate how unsteady air pockets flow over a plane.

Dialysis is a procedure that may be performed when a patient’s kidneys are unable to function normally. This procedure filters the patient’s blood by sending it through a machine that removes waste materials and excess fluid. In order to attach this device to the patient, a unique junction must be created between an artery and a vein in the patient’s wrist or upper arm. This may be done using a catheter. An arteriovenous fistulae is the name given to this connection.
In this work, which was published in the journal Physics of Fluids, researchers trained a computer using modeling strategies often used in the aerospace sector by utilizing machine learning methods. After that, the AI went on and optimized the geometry of an AVF in order to reduce the amount of unsteadiness that occurred in the blood flow.
