An NIRS matrix for detecting and correcting cerebral oxygen desaturation events during surgery and neuroendovascular procedures.

Background: Transcranial cerebral oximetry was developed for early detection of cerebral hypoxia and to avoid cerebral dysfunctions. However, near infrared spectroscopy (NIRS) data obtained during surgery are subject to intrinsic and extrinsic influences that have to be accounted for when interpreting the recordings.

Methods: We developed an NIRS matrix to provide brief information for specific intervention to correct changes of cerebral oxygen saturation (COS).
