这项研究调查了因阻塞性睡眠呼吸暂停综合征(OSAS)而昏昏欲睡的风险增加的人，是否在微睡眠期间而不是在清醒期间的时刻驾驶表现受损。根据标准的临床和多导睡眠图标准，24名持证司机被诊断为OSAS，他们在高保真驾驶模拟器中参加了长达一小时的驾驶，并通过同步脑电(EEG)记录来识别微睡眠。与同等路段上没有微睡眠的驾驶性能相比，司机在微睡眠期间的车辆控制明显恶化。性能下降的程度与微睡眠时间相关，特别是在弯道上。结果表明，在微睡眠期间，驾驶性能会下降。实时检测微睡眠，并确定这些在清醒和睡眠之间的转变如何损害司机的表现，与设计和实施对策相关，例如使用脑电技术的昏昏欲睡的司机检测和警报系统。(C)2007爱思唯尔有限公司。保留所有权利。
This study examined if individuals who are at increased risk for drowsy driving because of obstructive sleep apnea syndrome (OSAS), have impairments in driving performance in the moments during microsleep episodes as opposed to during periods of wakefulness. Twenty-four licensed drivers diagnosed with OSAS based on standard clinical and polysomnographic criteria, participated in an hour-long drive in a high-fidelity driving simulator with synchronous electroencephalographic (EEG) recordings for identification of microsleeps. The drivers showed significant deterioration in vehicle control during the microsleep episodes compared to driving performance in the absence of microsleeps on equivalent segments of roadway. The degree of performance decrement correlated with microsleep duration, particularly on curved roads. Results indicate that driving performance deteriorates during microsleep episodes. Detecting microsleeps in real-time and identifying how these episodes of transition between wakefulness and sleep impair driver performance is relevant to the design and implementation of countermeasures such as drowsy driver detection and alerting systems that use EEG technology.
