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(cHb),oxyhemoglobin(cHbO2) and the sum of hemoglobin(ctHb) 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
