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.
The vena cava has a thinner wall and a wider lumen than the aorta because of the lower blood pressures it has to deal with . Arterial blood pressure will be higher than venous blood pressure. The force generated by the heart as it pushes blood out requires thick vessel wall so it does not rupture. The vena cava simply carries blood back to the heart, there is much less force/pressure in the vena cava.
