In general, an individual’s “blood pressure" (systemic arterial pressure) refers to the pressure measured within large arteries in the systemic circulation. This number splits into systolic blood pressure and diastolic blood pressure. Blood pressure is traditionally measured using auscultation with a mercury-tube sphygmomanometer.
