The term ''blood pressure'' usually refers to the pressure measured at a person's [[arm|upper arm]]. It is measured on the inside of an [[elbow]] at the [[brachial artery]], which is the upper arm's major blood vessel that carries blood away from the heart. A person's BP is usually expressed in terms of the systolic pressure over diastolic pressure ([[Torr|mmHg]]), for example 140/90. |

Huyết áp (BP) là áp lực đẩy do sự tuần hoàn của máu trong các mạch máu, và là một trong những dấu hiệu chính cho biết cơ thể còn sống hay đã chết. Khi tim đập, BP thay đổi từ cực đại (áp lực tâm thu) đến cực tiểu (áp lực tâm trương).[1] The mean BP, due to pumping by the heart and resistance to flow in blood vessels, decreases as the circulating blood moves away from the heart through arteries. Blood pressure drops most rapidly along the small arteries and arterioles, and continues to decrease as the blood moves through the capillaries and back to the heart through veins.[2] Gravity, valves in veins, and pumping from contraction of skeletal muscles, are some other influences on BP at various places in the body.
The term blood pressure usually refers to the pressure measured at a person's upper arm. It is measured on the inside of an elbow at the brachial artery, which is the upper arm's major blood vessel that carries blood away from the heart. A person's BP is usually expressed in terms of the systolic pressure over diastolic pressure (mmHg), for example 140/90.
Ngày nay với công nghệ dự báo chuỗi thời gian bằng mạng nơ-ron nhân tạo, người ta còn có thể dự báo huyết áp của bệnh nhân trong một số ngày tới dựa vào các số liệu huyết áp của bệnh nhân trong quá khứ.
