What is blood pressure? Blood pressure – the pressure of blood in the large arteries of man. There are two blood pressure: systolic (upper) blood pressure – a pressure level blood at the time of maximum contraction of the heart. Diastolic (bottom) blood pressure – is the level of blood pressure at the moment of maximum relaxation of the heart. Blood pressure is measured in millimeters of mercury column, abbreviated mm Hg. Art. The value of blood pressure 120/80 means that the magnitude of the systolic (upper) pressure is 120 mm Hg. Art.
and the magnitude of the diastolic (bottom) blood pressure is 80 mmHg. Art. Why need to know the magnitude of blood pressure? Increased pressure for every 10 mm Hg. Art. increases the risk of developing cardiovascular disease by 30%. In people with high blood pressure in 7 times more likely to develop cerebral circulation (stroke), 4 times as often – ischemic heart disease, 2 times more likely to damage blood vessels feet. It is a blood pressure measurement should start looking for reasons for the frequent manifestations of discomfort, as headache, weakness, dizziness. In many cases, the pressure needs constant monitoring and measurement should be performed several times a day. What are some methods to measure your blood pressure? To measure blood pressure is now widely used 2 methods: Korotkoff This method, developed by the Russian surgeon ns Korotkov in 1905, provides for the measurement of blood pressure is a very simple tonometer consisting of a mechanical pressure gauge, cuffs and pear phonendoscope.
