Characterization of the Resulting Incapacitation Following Unexpected +Gz-lnduced Loss of Consciousness

ization of the resulting incapacitation following unexpected +G:- to occur. The very high onset +G (VHOG) capabilities induced loss of consciousness. Aviat. Space Environ. Med. 1987; of existing aircraft which can sustain the +G force 58:631-6. +Gz-induced loss of consciousness (G-LOC) results In In- will predispose aircrew to LOC episodes as long as capacitatlon whichcan be characterized by the unconscious there is a difference in the levels of the heart and 0 period (absolute Incapacitation) and a subsequent period of brain within the +Gz field. Detailed knowledge of the confusion/dlsorientatlon (relative Incapacitation). The sum of characteristics of +Gz-induced LOC are essential for the absolute and relative Incapacitation periods represents the total Incapacitation period and may be equated to the estimating the potential problems that can result from overall length of time a pilot would be In uncontrolled flight inflight LOC and for adding further insight into potential should G-LOC occur. Reviewing the centrifuge Induced G-LOC methods of prevention, intervention, and enhanced 0 episodes In 55 subjects allowed a detailed description of G- recovery. Advanced development of methods to reduce LOC. The absolute incapacitation period was 16.6 s with the the time of incapacitation are dependent on knowing subsequent relative Incapacitation being 14.5 s resulting In an overall total Incapacitation of 34 s. The G-LOC Incapacl- the length and characteristics of the typical LOC episode
