Systolic and diastolic blood pressure were measured using an aneroid sphygmomanometer.

Although I did not have a sphygmomanometer handy at the end of our walk, I am certain that I felt more relaxed and contemplative than when I began.

The advent of the stethoscope and sphygmomanometer—both of which require the patient and clinician to be silent—nudged this relationship from dialogue towards data.

The sphygmomanometer, invented in the 1890s, does not always give an accurate picture of a person’s blood pressure.

He who worships his sphygmomanometer as a thing apart and infallible will sooner or later come to grief.
