What is the spygmomanometer?

among many common tools used in the doctor's office is the one you are all familiar with, but whose real name is little known. This device is a sphegmomanometer that is used to measure blood pressure. Since the beginning of the 20th century, the spygmomanometer has been widely used and consists of a cuff located around the arm, as well as a pressure measurement device that the blood flows freely, and the pressure by which the blood flow is limited. The digital spygmomanometer often works with the touch of the button and the blood pressure data is displayed on the digital screen. Many manual spygmomanometers are also still used that usually require the doctor to work properly.

In the hand device, the pressure is displayed as the height of the mercury column in the tube. As the cuff is manually inflated, the height of the columnoses increases, and then decreases with pressure release. While the cuff blows out, the doctor usually listens to the main artery of the arm with a stethoscope.

When the blood flow begins to flow again after stopping the cuff, there is a rushing or pounding sound that the doctor is able to hear through the stethoscope. The pressure at which this occurs is recorded and is called systolic pressure. The cuff can be blown and the pressure at which the sound is no longer audible is also recorded and is called diastolic pressure. These two values ​​are a pair of numbers that are recognizable as the blood pressure value.

It is important that a person's blood pressure is measured when it is relaxed, otherwise the reading will be fake increased. Hormones such as adrenaline can dramatically increase blood pressure by reducing the blood vessels. For example, the WHO, for example, has been seriously frightened, will have increased blood pressure compared to someone watching TV. Precise values ​​are necessary to determine the heart of the heart and hence the rest of the body.

Using a manual spygmomanometer as wellyou. For those who have hypertension, this may be a valuable skill, because in this case it is often important to measure blood pressure. In addition to comfort, some patients are nervous when their blood pressure is used by a doctor, sometimes referred to as a laboratory coat syndrome. It can discard reading, so the ability to measure your own blood pressure at home is not only comfortable, but also medically relevant.
