Blood pressure is measured with a simple painless test usually using an electronic blood pressure monitor. This consists of an inflatable cuff that is wrapped around the upper arm (some blood pressure cuffs wrap around the forearm or wrist) and is attached to an electronic monitor that gives a digital readout of the blood pressure and pulse.
The systolic blood pressure number is always said first, and then the diastolic blood pressure number is given. For example, your blood pressure may be read as “120 over 80” or written 120/80.
Blood pressure is measured in millimetres of mercury (mmHg). However, usually the “mmHg” is not used when reporting the blood pressure.
