If you have ever had your blood pressure taken then you have felt the pressure applied by a typical g-suit. Just imagine that force being applied over most of your legs and your lower torso and that is about what you feel when the bladders inflate to their lowest pressure in order to restrict blood flow (human blood pressure at 1G peaks at just over 2 psi and drops to about 1.5 psi between beats).
As G increases, the apparent weight of the blood increases so the psi in the suit has to increase proportionally to counteract the increased head of pressure. This can be up to 5 times greater than the blood pressure cuff at your doctors. If your doc kept on pumping the cuff on your arm you would not thank him for it.
