Blood pressure measuring:
still called “RR” today – in honour of Riva-Rocci

In the 17th century an embittered scholarly argument was carried on about whether and how blood was transported through the body. The proponents recognized the connection between the pulse and heartbeat and developed the theory of blood circulation. But how was one to measure blood pressure?

Until long into the 19th century, blood pressure could only be determined directly. This invasive method involved pain and great risks (particularly of infection). Not until the development of a non-invasive procedure could the determination of the blood pressure be carried out in a simple and risk-free manner. Early devices of this kind included modified pulse measurers developed by physiologist Karl Vierordt (1818-1884) and the pathologist Samuel Siegfried von Basch (1837-1905). In 1896, the Italian physician Scipione Riva Rocci (1863-1937) demonstrated his principle for determining the blood pressure, which is still used today - he had created the prototype of the modern blood pressure measuring device. In his honour we still speak of “RR” (Riva Rocci), if we are speaking of the blood pressure. The term “mmHg” comes from the time when measurements were taken only with a mercury column. Riva Rocci’s method however still only involved feeling for the pulse with the fingers. In 1905, the Russian army surgeon Nikolai Sergejewitsch Korotkow (1874-1920) improved upon this method through use of a stethoscope.

Since the end of the 1920s, “Riva-Rocci” blood pressure measuring devices have been an absolute given in hospitals and doctor’s offices. Today, blood pressure measuring devices are convenient and easy-to-use – a must for doctors and assistants and increasingly for many patients as well.
