In military aviation, due to high-altitude flight operations, hypoxia training is mandatory and nowadays is mainly done as normobaric hypoxia training in flight simulators. During the last decade, scientific data has been published about delayed recovery after normobaric hypoxia, known as a "hypoxia hangover." Sopite syndrome is a symptom complex that develops as a result of exposure to real or apparent motion, and it is characterized by yawning, excessive drowsiness, lassitude, lethargy, mild depression, and a reduced ability to focus on an assigned task. In this study, we present the case of a 49-yr-old pilot who participated in normobaric hypoxia refreshment training in an F/A-18C Hornet simulator and experienced delayed drowsiness, even 3 h after the training. This case report demonstrates the danger of deep hypoxia. Hypoxia training instructions should include restrictions related to driving a car immediately after hypoxia training. In addition, hypoxia may lower the brain threshold for sopite syndrome.
在军事航空领域，由于高空飞行作业的需要，缺氧训练是强制性的，如今主要在飞行模拟器中进行常压低氧训练。在过去的十年中，已经有关于常压低氧后恢复延迟的科学数据发表，这种现象被称为“缺氧后昏迷”。索皮特综合征是一种由于暴露于真实或明显运动而引起的症状复杂，其特征为打哈欠、过度嗜睡、疲倦、乏力、轻度抑郁和集中注意力完成指定任务的能力下降。在本研究中，我们介绍了一名 49 岁的飞行员的案例，他在 F/A-18C 大黄蜂模拟器中参加了常压低氧恢复训练，即使在训练后 3 小时仍出现延迟性嗜睡。本病例报告说明了深度缺氧的危险。缺氧训练指南应包括与缺氧训练后立即驾车相关的限制。此外，缺氧可能会降低大脑对索皮特综合征的阈值。
