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.
Normally, the average pressure in systemic arteries is approximately 100 mm Hg, and which decreases to near 0 mm Hg in the great caval veins (superior and inferior vena cavae). The volume of blood that flows through any tissue in a given period of time (normally expressed as mL/min) is called the local blood flow.
