Berg test

The Berg test is an auxiliary test used to check whether blood pressure is normal. The closer the multiple arteries are to the tip, the lower the blood pressure. Blood pressure refers to the lateral pressure of the blood in the blood vessel per unit area of ​​the blood vessel wall, that is, the pressure. Because blood vessels are divided into arteries, capillaries, and veins, there are also arterial blood pressure, capillary blood pressure, and venous blood pressure. Generally speaking, blood pressure refers to arterial blood pressure. When blood vessels dilate, blood pressure drops; when blood vessels constrict, blood pressure rises. The Berg test is designed based on the principle of blood pressure. Through this test, the lesion site and the corresponding symptoms can be judged.
