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.
Wrist Blood Pressure Monitors use the radial artery to measure blood pressure instead of the more commonly used brachial artery. The key is to place the monitor on your wrist properly, just above the wrist bone and then to hold your wrist up level with or above your heart. While measuring blood pressure the cuff always needs to be level with the heart for an accurate reading, this is true with arm cuffs as well.
