Introduction[edit | edit source]
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. It is measured in millimeters of mercury and expressed in terms of systolic pressure over diastolic pressure.
- Systolic pressure refers to the maximum pressure within the large arteries when the heart muscle contracts to propel blood through the body.
- Diastolic pressure describes the lowest pressure within the large arteries during heart muscle relaxation between beating. [1]
Blood pressure is one of the most commonly measured clinical parameters and blood pressure values are major determinants of therapeutic decisions.[2]
Arterial pressure directly corresponds to
- Cardiac output,
- Arterial elasticity
- Peripheral vascular resistance.
Blood pressure is remarkably easy to alter and can be affected by many activities.[1]
