The top number of your blood pressure reading tells you the force of the blood against artery walls when your heart beats. It is called systolic pressure. The bottom number tells you what your blood pressure is when your heart is at rest between heartbeats. It is called diastolic pressure.

Apple Watch alone cannot take a blood pressure reading. The only medically accurate and validated way to do so today is by stopping the blood flow by inflating a blood pressure cuff around your upper arm and then deflating it while listening for changes in your arteries.

There are two pressures measured: (1) the systolic pressure (the higher pressure and the first number recorded), which is the force that blood exerts on the artery walls as the heart contracts to pump the blood to the peripheral organs and tissues, and (2) the diastolic pressure (the lower pressure and the second ...

Oscillatory Blood Pressure Monitoring Devices Oscillatory devices produce a digital readout and work on the principle that blood flowing through an artery between systolic and diastolic pressures causes vibrations in the arterial wall which can be detected and transduced into electrical signals.

They're both measured in millimetres of mercury (mmHg). As a general guide: high blood pressure is considered to be 140/90mmHg or higher (or 150/90mmHg or higher if you're over the age of 80) ideal blood pressure is usually considered to be between 90/60mmHg and 120/80mmHg.
