Detailed explanation-1: -Systolic blood pressure is measured when the heart ventricles contract. Diastolic blood pressure is measured when the heart ventricles relax. A systolic pressure of 115 millimeters of mercury is considered normal, as is a diastolic pressure of 70. Commonly, this pressure would be stated as 115 over 70.
Detailed explanation-2: -At peak systole, the blood pressure in the aorta reaches approximately 120 mmHg under normal healthy human adult conditions. At the point that the aortic valve closes, the pressure in the aorta is approximately 100 mmHg.
Detailed explanation-3: -ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg. high blood pressure is considered to be 140/90mmHg or higher. low blood pressure is considered to be below 90/60mmHg.
