Description
Summary:In some cases, temporary or permanents occlusion of the arteries, which participates the cerebral blood flow, are needed during surgery. The exact and fast EEG monitoring of the brain functions and their dynamic changes is an important way to minimize the neurological deficits during surgery. The goal of this study is to develop the integrated EEG monitoring system with expandability. The system consists of a data acquisition, a waveform memory management, and a data analysis part. At the present stage, it can display waveform, spectrum and topography change of each frequency component on arbitrary electrode groups, and DRT (deviation ratio topography) in real time. In this stage, the system warns the operator by the alarm when the measured EEG changes significantly. This function makes possible to know the patient's condition without seeing the monitoring system.
