Blood pressure is divided into arterial blood pressure, capillary blood pressure, and venous blood pressure, but generally refers to arterial blood pressure. The arterial blood pressure is determined by cardiac output and peripheral resistance. The blood pressure when the ventricle contracts and blood is pushed into the artery is measured. It is called systolic blood pressure, which is the highest blood pressure in the blood vessels, and when the ventricles are expanded and the blood is not pushed out, the artery wall has elasticity and compresses the blood, so the blood pressure does not become zero. .

Blood pressure measurement methods are classified into direct measurement methods and indirect measurement methods.
