Near-infrared spectroscopy monitoring provides a practical method to follow trends in superficial cerebral cortex oxygenation during and after cardiovascular surgery. Determination of the limits of cerebral pressure-flow autoregulation is now possible using processed oximetry signals in relation to arterial pressure.
近红外光谱监测提供了一种实用方法,可用于追踪心血管手术期间及术后大脑浅表皮质氧合的变化趋势。利用处理后的血氧饱和度信号与动脉压的关系,现在可以确定脑压力-血流自动调节的限度。
