blood pressure
Blood pressure is the heart’s blood drive to send it through the blood vessels to feed all parts of the body. It is loaded with food and oxygen and works to pull out carbon dioxide, waste and toxins from the cells. Blood presses the wall of blood vessels, which is what we call blood pressure.
The normal human blood pressure rate in the case of rest, stability and distance from the acute tensions and feelings, is less than (120/80) mm / Hg, where the number (120) to the state of constriction of the heart and push blood to parts of the body and often between (110 – 139). The number 80 refers to the condition of the diastolic heart at the time of rest and relaxation. Reading is normal between 70 and 8, and any decrease or increase in this number indicates an unhealthy condition. At high blood pressure, (140/90) mm Hg, and when blood pressure is lower than (100/60) mm Hg.
Blood pressure is one of the things that people should be warned about because they cause a lot of problems in the human body if they rise or fall from the normal level, such as strokes, heart attacks, etc., and complications of pressure problems may lead to death.
Methods of measuring pressure
There are many methods of measuring blood pressure, including what is simple and can be used easily and there are some complex devices that need expertise in order to analyze the information issued, including:
Traditional device
Pressure measurement by a device (Sphygmomanometer): This device is a belt that contains a bag connected to a standard device is either a liquid or a meter, and this bag is filled with air through a hand pump connected to it, and attached to the device a hand-held device enables the doctor to hear blood flow during measurement, and this device takes two readings Higher reading to systolic blood pressure and lower reading to diastolic blood pressure. Blood pressure is measured through the arm. The device must be placed at the same arm level for accurate reading. The person undergoing the examination should be in a state of rest and tension.
Electronic device
The device operates in the same way as the traditional device, but the electronic device blows and unloading the belt from the air, and the process of pulse sensor is automatic and then show the results separately, many want to acquire this device because of its ease of use.
