Fundamental study of nursing arts for higher brain function disorder patients

使用BIS监测仪Vista （Nihon Kohden; a -3000）对正常受试者进行检查，以评估意识水平，目前为提高昏迷患者的意识水平而采用无背部支撑的坐姿。与没有背部支撑的坐姿相比，有背部支撑的坐姿的BIS值降低了，BIS值是意识水平的指标。此外，由于持续无背部支撑的坐姿也会降低BIS值，因此我们认为，不仅需要无背部支撑的坐姿，还需要其他护理技术的配合，以提高意识水平。

The effects of the sitting position without back support currently performed in order to improve the consciousness level for unconscious patient were examined for normal subjects using the BIS monitor Vista (Nihon Kohden ; A-3000) which can evaluate a consciousness level. The BIS value which is an index of a consciousness level, was reduced in the sitting position with back support compared with the sitting position without back support. Moreover, since a BIS value was also decreased by continuing the sitting position without back support, it is thought that there is need not only the sitting position without back support but also other nursing arts be used together for an improvement of a consciousness level.
