What Is the Normal Blood Pressure Range? Chart | 合法醫療器材資訊網

Blood pressure[1] is the force applied by the blood over the inner walls of the arteries. Although the average blood pressure (120/80mmHg) for a person remains constant, it shows minor fluctuations throughout the day, declining while relaxing and momentarily increasing while being excited or under stress[2].

It is produced primarily by the contraction of the heart[3] muscle. Its measurement is recorded by two numbers.
