Korotkoff sounds: a century-old enigma of physics is finally solved

​

Invented over a century ago, it certainly is the most common clinical examination: each one of us already had its blood pressure measured using an inflatable cuff and a stethoscope. However, the fundamental principle of this measurement remained until now a mystery in the world of physics. Researchers from the Institute Physics for Medicine Paris (Inserm, ESPCI Paris-PSL, CNRS – France) have solved this enigma by studying in details the mechanical phenomena occurring in the arm when blood pressure is measured. The results are published on October 4th 2023, in frontpage of Science Advances. the paper: "The fundamental mechanisms of the Korotkoff sounds generation".
