摘要
随着现代高性能战机的机动性能不断提升,持续性正加速度导致的意识丧失(G-LOC)越来越成为影响飞行安全和制约战机性能发挥的主要威胁。近红外光谱技术(NIRS)是近年涌现出的一种评估生物组织氧合水平的非侵入式光学技术,可对局部脑区血流量和氧含量的动态变化进行实时监测,在+Gz所致的飞行人员脑缺血缺氧状态监测方面具有潜在应用价值。该文围绕NIRS技术的基本原理和发展现状,在飞行员+Gz暴露脑功能状态监测、G-LOC防护生理训练和效果评价中的应用,以及NIRS在加速度生理学研究领域的未来发展方向等进行综述,以期为关注G-LOC监测预警与防护问题的研究者提供参考和借鉴。
With the continuous improvement of the maneuvering performance of modern high-performance fighter jets,the loss of consciousness caused by sustained positive acceleration(G-LOC)has increasingly become a threat to flight safety and an obstacle to the performance of fighter jets.Near infrared spectroscopy(NIRS)is a non-invasive optical technique that has emerged in recent years to evaluate the oxygenation level of biological tissues.It can not only monitor the real time dynamic changes in blood flow and oxygen content in local brain regions,but be potentially used for the monitoring of cerebral ischemia and hypoxia induced by+Gz in flight personnel.This article summarizes the basic principles and developments of NIRS technology,its applications in monitoring a pilot’s brain function during+Gz exposure,G-LOC protection physiological training and effect evaluation,and the future research on NIRS in the field of acceleration physiology.It is expected to provide reference for researchers who are interested in G-LOC monitoring,early warning and protection.
