Near-infrared spectroscopy (NIRS) during and after cardiopulmonary resuscitation: A systematic review and meta-analysis

Higher rSO₂ values during CA are consistently associated with increased rates of ROSC, with delta rSO₂ values having the highest predictive power. However, from a practical point of view, retrospectively calculating delta values poses a significant limitation which could be overcome by rather using real-time trends. Also, the implementation of NIRS in postresuscitation care could be an additional component of early multimodal prognostication after CA as we showed that higher initial rSO₂ values after ROSC are associated with a favourable neurological outcome.
