With the help of blood pressure measurement of the pressure of a blood vessel is determined. A distinction is made between measurements of venous pressure, arterial pressure, pulmokapillären pressure (measured in Lungenkapillargebiet) and the pulmoarteriellen pressure (measurement of the pulmonary artery). Since the blood pressure measurement is carried out very easily, its role in medical use, a major role.
As blood pressure is defined as the pressure in the arteries (arteries) of the systemic circulation. With each beat of the heart, there is variation between a minimum value (diastolic pressure) and a maximum value (systolic value). This survey is a blood pressure measurement with an inflatable cuff that can be applied to the arm or leg. This indirect measurement was developed in 1896 by physician Scipione Riva-Rocci (1867-1937). Even today, this measurement method to Riva-Rocci and named with the initials RR. There are also the direct measurement, in which the blood pressure is measured with a needle lying on the blood stream. This method is applied but only in an operating room during an intensive therapy.
The normal blood pressure in adults is a diastolic pressure below 90 mmHg and a systolic pressure of less than 140 mm Hg (140/90) is. If the value of 140/90 mmHg, it is called a high blood pressure (hypertension). If blood pressure is a systolic value below 100 mmHg, and he is considered too low (hypotension). This diastolic value is usually lower than 65 to 60 mmHg. An ideal blood pressure of 120/80 mmHg, a value.
Determined the blood pressure is usually by individual measurements. For certain diseases it is recommended that long-term measurement, such as blood pressure measurements during the day or night. In this case, a 24-hour measurement is made, in which the blood pressure monitor is attached.
