What does the pressure of the g-suit feel like?
Fighter pilots need a lot of pressure, more than 5 psi, which equals 258 mm Hg. To check blood pressure, the cuff is usually pumped up to 200 mm Hg before releasing the pressure. A good blood pressure reading is below 120/80 mm Hg. By comparison, research on g-suits and MAST (Military/Medical Anti-Shock Trousers) has shown that the pressure required to relieve Orthostatic Intolerance (OI) symptoms is 40-50 mm Hg. When manually inflated, the pressure of the g-suit for Orthostatic Intolerance (OI) feels comfortable, gentle, and even. (It should not hurt.) Many support stockings are available in much lower pressure like 10-20 mm Hg.
