How to write millimeters of mercury in mmHg.

The unit of blood pressure mmHg is pronounced millimeters of mercury or millimeters of mercury. Blood pressure is the lateral pressure of blood within a blood vessel against the vessel wall, usually referred to as blood pressure is arterial blood pressure, divided into systolic and diastolic blood pressure. It is measured mostly in the brachial artery and is measured in mmHg, short for millimeters of mercury, also known as millimeters of mercury. Blood pressure in mmHg is often measured directly by an electronic sphygmomanometer or a mercury sphygmomanometer.

Normal blood pressure is less than 120mmHg systolic and less than 80mmHg diastolic, normal high blood pressure is 120 to 139mmHg and 80 to 89mmHg. usually read blood pressure, first read systolic, then read diastolic, such as 110/70mmHg, read systolic blood pressure of 110mmHg, diastolic blood pressure of 70mmHg.

Origin and Principle:

Millimeter of mercury comes from the Torricelli experiment. The principle is to balance the atmospheric pressure P with the static pressure generated by the column of mercury, so the height of the column can measure the size of atmospheric pressure. In addition to atmospheric pressure measurements, the unit is also used in high vacuum engineering (especially in environments where the pressure is so low that viscosity disappears), blood pressure measurements, intraocular pressure measurements, and so on.

How to keep your blood pressure stable:

You need to control your blood pressure in your daily life by eating a light diet, low salt and low fat. Change your lifestyle and work regularly. Exercise regularly. Keep your emotions stable and keep your bowels clear. Regular monitoring of blood pressure, blood pressure abnormalities found in a timely manner to avoid delays.
