摘要：

Dynamic changes of regional cerebral oxygenation (rSO(2)) were measured simultaneously to laser Doppler flowmetry in a 35-year-old female during cerebral aneurysm surgery. In addition, to demonstrate the uselessness of the absolute values obtained by the INVOS 3100, cerebral oximeter readings from a pumpkin (''Styrian Cucurbita'') are demonstrated. The results of the present study and of other reports discussed in this paper demonstrate that the INVOS 3100 cerebral oximeter should not be used at this moment as a measure reflecting absolute rSO(2) values. However, it seems to be relevant that the INVOS 3100 system can monitor the dynamic changes in rSO(2), although limitations have to be taken into consideration.
