摘要：

应用近红外光谱法,研究分析汽车驾驶员在振动状态下的脑部血氧参数变化,探讨车辆振动对脑氧参数的影响。实验过程中应用近红外光谱法监测试验人员脑氧参数。经方差分析发现实验人员经车辆振动后脑部各血氧参数有显著性变化。实验结果表明汽车振动对脑部血氧参数还原血红蛋白的浓度(c_Hb)、氧合血红蛋白的浓度(c_HbO2)、血红蛋白总量的浓度(c_tHb)有显著性影响,且不同频率振动的影响显著性不同,其中4.5Hz的振动对脑氧参数影响最大；但振动对脑部组织血氧饱和度(tissue oxygen index,TOI)的影响极小。

Abstract:

The effects of vibration on oxygenation response were assessed. The cerebral blood parameters were monitored and recorded using near infrared spectroscopy during the experiment. Based on variance analysis, remarkable variations of the parameters in the cerebral tissue blood were found(P<0.01). The result of the experiment demonstrated that concentration of hemoglobin(c_Hb),oxyhemoglobin(c_HbO2) and the sum of hemoglobin(c_tHb) are significantly influenced by vehicle vibration.Furthermore, the influence of different frequencies is significantly different, the influence of 4.5Hz vibration is the most remarkable. Whereas, the tissue oxygen index (TOI) is little influenced by all the vehicle vibration of the three frequencies.

Key words: near infrared spectroscopy, cerebral oxygenation, vehicle vibration
