determined as follows: two or three fingers are placed on the artery and they are squeezed by one of the fingers until the second finger (or two fingers) no longer perceive pulse beats. The pulse voltage is determined by the force that must be applied to stop the pulse wave passing through the artery. With high blood pressure, the pulse becomes hard, at low - soft.
It is necessary to investigate the properties of the pulse on different arteries, comparing them on the arteries of symmetrical areas. This way it is possible to identify a violation of blood flow, other pathological conditions.
