May support NIRS for cerebral oxygenation trends in CV surgery; leaves open outcome benefits pending RCTs.
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.
