Arterial Blood Pressure : When blood pressure is measured using a sphygmomanometer, the upper value is the systolic pressure and the lower value is the diastolic pressure. Normal systolic pressure is less than 120 mmHg, and normal diastolic pressure is less than 80 mmHg.
Aortic pressure : The difference between the systolic and diastolic pressures is the aortic pulse pressure, which typically ranges between 40 and 50 mmHg. The mean aortic pressure (Pmean) is the average pressure (geometric mean) during t
