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.
High blood pressure is a common disease in which blood flows through blood vessels (arteries) at higher than normal pressures. Measuring Blood Pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood. High blood pressure, sometimes called hypertension, happens when this force is too high. Health care workers check blood pressure readings the same way for children, teens, and adults. They use a gauge, stethoscope or electronic sensor, and a blood pressure cuff. With this equipment, they measure: Systolic Pressure: blood pressure when the heart beats while pumping blood
