Abstract
We have confirmed the RSAF's conclusions in previous experiments, but have also demonstrated that the protective qualities of the RAF's system could be greatly improved by increasing the G-suit pressure to 3.2 times the breathing pressure. However, the possible protective values of G-suit/PPB rations other than 1.0 or 3.2, have not been examined in detail. Further evaluation of G-suit/PPB rations appears necessary now, since PPB is again being considered as an alternative method of providing emergency protection against hypoxia to aircrew flying above 45,000 ft. The present study was undertaken to determine which G-suit/PPB ratio would afford the optium protection against the adverse physiological disturbances of PPB.
