- At a time when the mechanics of respiration and circulation were a mystery, his series of animal experiments led to the first understanding of blood pressure. He inserted a tube into a mare’s artery and observed the pulsing of blood into a twelve-foot glass tube, thereby becoming the first person to measure blood pressure.

Jul 28, 2011 · Physicians of antiquity used the examination of the pulse not only for diagnosis, but also as an indicator of prognosis. This paper will review the history of the assessment of pulse from ancient times to the present.

Galen, a Roman physician, was the first to write about the human heart, saying it is the source of the body’s heat. His book was translated, became a best-seller worldwide and remained unquestioned for centuries. Among his inaccuracies he thought the heart only had two chambers when it actually has four.

Even around the year 1000, the famous Persian physician Avicenna was still taking Galen’s conclusions at face value, and spreading inaccuracies in his books. SaveSaveSaveSave
While studying the human anatomy “first hand” becomes more common, the reference to past publications still overshadows actual observations. Even the famous Leonardo Da Vinci fell for it and drew a heart with only two chambers. SaveSaveSaveSave
In 1543, Andreas Vesalius published “De Humani Corporis Fabrica,” a book he wrote after studying real corpses. For the first time it is acknowledged that the heart has four chambers and not two. But it’s not over! At that time the heart’s function is still under debate. SaveSave
The first study on blood circulation was published in 1628 by William Harvey—an English physician. He came to the conclusion that the heart acts as a pump. At that point it wasn’t clear that blood circulated, but after a little calculation he was pretty sure that blood is not “consumed” by the organs. The physician then concluded that blood must be...
The first measurement of what was then called “the force of blood” is described in the book “Haema staticks” in 1733, by Stephan Hales. He used a water manometer to measure the blood pressure in the arteries of various animals. SaveSave
The stethoscope, an essential tool for taking blood pressure, is invented by French doctor René Laennec in 1817. Doctors don’t need to put their ears to patients’ bodies anymore! The auscultatory method he developed uses the stethoscope to tell the difference between the systole and diastole pressures. SaveSave
In his doctoral thesis “Recherches sur la force du cœur aortique” published in 1828, French physician Jean Poiseuille is the first to show how to measure blood pressure with a mercury manometer. To quantify blood pressure Jean uses the “Centimeters of Mercury” unit (cmHg), which is still being used by doctors nowadays. SaveSave
The first device to estimate blood pressure externally, in a non-intrusive way, was the sphygmograph—from the Greek words for “pulse” and “write”. The precursor of today’s blood pressure cuffs was invented by the German physiologist Karl von Vierordt in 1854. SaveSave
Italian internist Scipione Riva-Rocci introduced the first blood pressure monitor—a sphygmomanometer with the pneumatic cuff invented by Dunlop. Still, the 2-inch wide cuff is not big enough to provide accurate measures. SaveSave

His device consisted of a water or mercury-filled rubber ball connected to a manometer. The rubber ball was then pressed against the radial artery until the pulse was obliterated and the blood pressure was then estimated using the manometer and palpation was used to determine when the arterial pulse disappeared.
Aug 22, 2019 · The history of the arterial pulse entails the discovery of pulse, blood pressure... The arterial pulse has been the most basic sign of life for centuries. The radial pulse palpation has been pictured in the crest of the Royal Academy College of Physicians since 1628.

Jun 29, 2023 · The history of blood pressure monitoring originates in the 16th century from Sir Stephen Hales’ experiments involving directly inserting a tube in an artery. Since then, the practice has been (thankfully) improved not to involve invasive manoeuvres.
Apr 1, 2024 · Besides PPG, applanation tonometry , radar , ultrasound , and pressure sensors have been used for pulse waveform acquisition. Pulse arrival time (PAT) and PWV are similar concepts often used interchangeably.
Jun 14, 2021 · Monro-Kellie’s theory was a starting point for understanding pathological phenomena and possible variations on ICP. One of the elements investigated, even during the consolidation of the theory, was the intracranial pulse.
