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.
Blood pressure is a measure of the force of blood inside an artery. Most people use an automatic device to measure blood pressure at home. This device works by inflating a cuff around the upper arm to temporarily stop the flow of blood in an artery.lood pressure is a measure of the force of blood inside an artery.
