Arterial and venous pressures are dependent on the patient's access and the QBS. Ideally, the arterial pressure should be no more than - 250, and the venous no greater than 300. But, as mentioned above, it depends much on the patient's access.
Contraction and relaxation of the ventricles in the heart lead to maximum (systolic) and minimum (diastolic) blood pressure values in the aorta as well as other arteries. Typical systolic and diastolic pressure values of 120/80 mm Hg are shown. The mean arterial pressure is shown to be approximately 93 mm Hg.Following ventricular systole, pressure in the left ventricle rapidly drops to below that in the aorta, thus, causing the aortic semilunar value to close.hile systolic and diastolic arterial blood pressure values are important measurements and have tremendous diagnostic value (see Table 1), it is the mean arterial pressure (MAP) that drives blood through the vasculature from the arteries to arterioles, capillaries, venules, veins, and back to the heart.
