Automatic noninvasive measurement of arterial blood pressure

This paper discussed arterial blood pressure measurement. Because of the high rate of hypertension in the adult population and its harmful effects, the measurement of arterial blood pressure is of great clinical significance. Manual sphygmomanometry, developed more than a hundred years ago, is currently the most accurate non-invasive technique for arterial blood pressure measurement. Since manual sphygmomanometry requires a well-trained examiner, only single measurements of blood pressure will generally be performed by a physician during a given visit. This single measurement only provides partial information since blood pressure changes spontaneously. The available automatic blood pressure meters, mainly based on oscillometry, can be used at home but some of them are of low accuracy. A direct technique for the measurement of systolic blood pressure by means of the detection of the blood pressure pulses' reappearance during cuff deflation has the potential to provide accurate automatic measurement of systolic blood pressure.
