Exposure of pilots to high sustained +Gz (head to feet) or rapid onset of +Gz can produce a variety of pathophysiologic effects ranging from the loss of peripheral vision to total blackout and, finally, G-induced loss of consciousness (G-LOC). A G-LOC research program divided into four phases has been organized at USAFSAM/Crew Technology Division. In contrast to previous studies in acceleration, this program will focus exclusively on the ultimate problem in G-LOC; namely, inadequate cerebral perfusion leading to impaired brain energy metabolism, structure and function. The primary objective of this research program is to identify and arrange chronologically the numerous physiological and biochemical alterations in the brain that comprise the mechanism of G-LOC.
飞行员长时间暴露于持续的高 +Gz（从头到脚）或快速出现的 +Gz 时，会产生多种病理生理效应，从周边视觉丧失到完全昏厥，最终导致 G 诱导的意识丧失（G-LOC）。美国空军安全部队中心/机组人员技术部已组织了一个分为四个阶段的 G-LOC 研究项目。与以往的加速度研究不同，该项目将专门关注 G-LOC 中的最终问题；即脑灌注不足导致脑能量代谢、结构和功能受损。该研究项目的主要目标是识别并按时间顺序梳理大脑中构成 G-LOC 机制的众多生理和生化改变。
