Continuous monitoring of dynamic changes of transcranial regional cerebral oxygenation (rSO2) was performed in 7 healthy volunteers (mean age 40.9 +/- 12.6 years; range 25-62 years) during normo- and hyperbaric oxygenation (HBO at 2.5 and at 1.95 ATA) using an INVOS 3100 cerebral oximeter. A significant change between HBO and control phase could be found in rSO2, alterations (p < 0.05; ANOVA, Tukey test). The results suggest that the calculation of rSO2 may be a useful method to monitor changes of oxygen saturation under hyperbaric conditions. However, the absolute quantification of rSO2 is useless at the moment and needs further investigation.
使用INVOS 3100脑氧饱和度仪，对7名健康志愿者（平均年龄40.9±12.6岁；范围25 - 62岁）在常压和高压氧疗（2.5和1.95 ATA的高压氧）期间的经颅局部脑氧合（rSO2）动态变化进行了连续监测。在rSO2中可发现高压氧疗与对照阶段之间存在显著变化（p<0.05；方差分析，Tukey检验）。结果表明，rSO2的计算可能是监测高压条件下氧饱和度变化的一种有用方法。然而，目前rSO2的绝对定量尚无用处，需要进一步研究。
