Near-Infrared Spectroscopy (NIRS) as a Tool to Prevent Cerebral Desaturation in Newborns with Bradycardia Events: A Systematic Review.

Near infrared spectroscopy (NIRS) is a non-invasive tool providing real-time continuous measurement of regional cerebral blood oxygenation and indirect blood flow. The aim of this review is to determine the best evidence to guide the use of NIRS to detect and avoid abnormalities of cerebral perfusion and oxygenation in newborns with bradycardia.
