前言 高G飞行时,飞行员完全丧失意识虽然是潜在灾难性的,但相对来说不常见。飞行员较多报告的是:在实际空战(中)动作时出现短暂的、各种各样的发作,诸如精神紊乱、遗忘、淡漠、情境意识消失,或双手软弱、抽动。这些空战动作的特征是有快速和短暂的Gz暴露,短时间的较低水平的G以及小于1G的飞行。这些发作就是ALOC的特征,但目前尚未受到足够的重视。本文提出了解释这些现象的可能机制。讨论 脑组织的各个区域具有不同的代谢需求及不同的灌 INTRODUCTION The complete loss of consciousness of pilots when flying in high G, while potentially catastrophic, is relatively uncommon. Pilots report more often: brief episodes of various kinds of attacks such as mental disorders, forgetfulness, apathy, loss of situational awareness, or weakness and twitching of their hands during actual air combat (mid) movements. These air combat movements are characterized by fast and brief Gz exposures, short-duration, low-level G, and less than 1-G flights. These seizures are the characteristics of ALOC, but not yet enough attention. This paper presents possible mechanisms for explaining these phenomena. Discussion Various areas of brain tissue have different metabolic needs and different irrigation
