It includes a sensor strapped to the wrist which can measure the pressure in the aorta, the main artery close to the heart, where high blood pressure does most damage. A sensor in the watch records the pulse wave of the artery, which is then fed into a computer together with a traditional blood pressure reading from a cuff. In most people the pressure in the aorta is 10mm Hg lower than in the arm, but in some, especially younger people, it is as much as 30mm Hg lower.
How To Measure Blood Pressure, And What It All Means. Here are the tools: A Stethoscope and a Sphygmomanometer. Make sure you place the round end of the stethoscope 'under' the blood pressure cuff. You inflate the sphygmomanometer (blood pressure cuff) to a little above 180 mm Hg. This collapses the major arteries to the arm (that's why it is uncomfortable). Then you slowly release air by gently turning the air valve, and watch the pressure drop.
