Blood pressure is the pressure generated in the artery wall. Peak pressure occurs when the left ventricle contracts and is called the systolic pressure. Diastolic pressure is the lowest pressure that occurs when the heart is resting. Blood pressure is usually described as the ratio of systolic to diastolic pressure, with normal adult values ​​ranged from 100/60 to 140/90. The average normal blood pressure is usually 120/80.
