Measurement of cerebral oxygenation state in anaesthetized children using the INVOS 5100 cerebral oximeter

Abstract

The large range and the poor agreement of cerebral oxygenation values between the two oximeters makes it difficult to define a normal value. Cerebral oxygenation readings by these monitors, based on one single point measurement during anaesthesia, should be viewed with caution. Actually, there may be little indication for routine use of such monitoring during general anaesthesia.
