I am seeing more and more work done on the measurement of central blood pressure, but there is still a fundamental lack of understanding on its value and interpretation of results, so I thought I’d give it a quick overview. Central blood pressure (CBP) refers to the pressure within the aorta, the ...

Tech souvenir of the week: The Von Basch Sphygmometer
In 1881, Samuel Siegfried Karl Ritter von Basch invented the sphygmometer. A mercury or water-filled rubber ball, connected to a manometer, was pressed against the radial artery until the pulse was obliterated. The blood pressure was then estimated using the manometer. Palpation was used to determine when the arterial pulse disappeared. So indeed, contrary to popular belief, the early devices were filled with liquid (water or mercury) and not air. It is only in 1889 that Potain, in France, improved all the compression devices by replacing water and mercury in the devices with air, substantially improving their accuracy. From this moment on, air became the compression medium of choice.

There are several used pacemakers in the HealthWorks Collection. It does sound a bit gore, because these pacemakers are “used” in the sense that they came out of people’s bodies… But they are beautiful examples of gradual minimisation and of how technology will inevitably bend to the needs o...
