Abstract : Decompressions simulating the effect of a small structural failure in the cabin of an aircraft operating above 60,000 ft. have been studied in the monkey (Macaca mulatta). The profiles have been based on recent data applicable to a supersonic transport. Neurological, electrocortical and neuropathological examination has established that during a triangular profile of peak altitude not exceeding 36,000 ft. and of duration not 8 min. above 10,000 ft., the spontaneous electrical activity of the brain is maintained and there is no subsequent evidence of brain damage. Such a profile is unlikely to be fatal and will not lead to permanent brain damage in healthy passengers breathing air provided pulmonary ventilation is maintained. It is considered that cabin pressure should remain within this profile in the event of a decompression. (Author)
