Near Infrared Spectroscopy (NIRS)

NIRS is one of the most recent and promising methodologies for assessing real time brain oxygenation and perfusion.

Near Infrared Spectroscopy (NIRS)


This technique includes cerebral hemodynamic assessment, where it is possible, through the application of optodes / sensors on the cranial scalp, to infer oxygenation and tissue blood flow.

Studies show that changes visualized in the NIRS may have prognostic relationships in newborns with asphyxia, congenital heart disease and prematurity, and may also be associated with loss of the brain’s self-regulating mechanism. It is considered the earliest biomarker of abnormal tissue oxygenation.
