High blood pressure 4 The number of patients with hypertension remains high. Now, has exceeded 330 million , and the age is becoming younger. As a chronic disease, there is no complete cure for hypertension. Its disease is due to the interaction results of various reasons, environmental reasons, genetic causes, etc.
patients with hypertension must pay attention to maintaining blood pressure in their bodies, because this chronic disease is related to heart disease, stroke , and kidney disease.
A accurate measurement is an important link for patients with hypertension to better control hypertension. However, according to data surveys, it is shown that some patients' blood pressure measurement is not standardized, resulting in poor blood pressure control. Today we will learn how to measure blood pressure.
1
First understand, the formation of blood pressure
The blood pressure of the human body, refers to the measurement of the blood vessel wall generated per unit area when blood flows in the blood vessels.
Due to blood vessel transfer, veins and capillaries, there are also Artial blood pressure, capillary pressure and Vinary pressure . However, the blood pressure we talk about in our lives refers to the blood pressure of the human artery. So when measuring, should we measure the left arm or the right arm?

When measuring blood pressure, is it necessary to measure the left arm or the right arm? If you do not understand these questions, it may be equivalent to the white test
Generally, blood pressure is measured by , as measured by the upper right arm , the blood pressure measured by the left arm is usually lower than the right arm, and the right arm is the first choice to measure blood pressure under the same conditions , if the blood pressure between the two arms is different , the right arm should also be the basis .
Blood pressure is the pressure measured by blood flowing into the blood vessel wall. The blood pressure of various blood vessels is different, so there are arterial blood pressure, capillary blood pressure and venous blood pressure.
However, if measures blood pressure for the first time, it is recommended to measure the blood pressure of the two upper limbs . In the future, when measuring blood pressure, choose the upper limb with higher blood pressure, because some people will have a certain difference in the blood pressure of the two upper limbs. If the difference in blood pressure is greater than 20mmhg, you should consider the stenosis of the upper limbs on the hypotension side.
It is recommended to perform color Doppler ultrasound examination on the cervical blood vessels and bilateral upper limb blood vessels, so that can be clearly diagnosed. In life, blood pressure measurement must be selected to select upper limbs with higher blood pressure, so as to effectively avoid significant increase in blood pressure and acute cardiovascular disease events.

How often should the blood pressure be tested?
First of all, General population . For a healthy person who is not at risk of cardiovascular disease, the blood pressure in the body needs to be measured once every six months.
followed by for the first time to diagnose patients with hypertension. People like should measure blood pressure for more than three days and exclude the impact of other diseases. Hypertension should be once in the morning and evening every day, and records should be made.
Finally, The patient with blood pressure not meeting the standard or fluctuations after meeting the standard should insist on measuring blood pressure until the blood pressure control is stable.

electronic blood sphygmomanometer and mercury blood sphygmomanometer , which one should I buy?
Nowadays, many patients with hypertension will buy electronic blood pressure monitors themselves and measure them at home, but when purchasing, they don’t know whether to choose electronic blood pressure monitors or mercury blood pressure monitors.
In fact, the mercury blood sphygmomanometer is based on "ausalverization method" , and is called "gold standard" . The measurement is originally standard, so the mercury blood sphygmomanometer is measured more accurately.
Most electronic blood sphygmomanometers are based on "oscillometry" . In terms of measurement principle, has defects, , but the measurement results of electronic blood sphygmomanometers are acceptable, and the deviation is relatively small.
If we look at the operation point of view, Mercury blood sphygmomanometer is more troublesome to operate , but electronic blood sphygmomanometer is even simpler, so it is recommended that people with have a certain medical foundation use mercury blood sphygmomanometer, and electronic blood sphygmomanometers are recommended for people who have never measured their blood pressure.
