cerebral near-infrared spectroscopy
Also written as: NIRS — Near-Infrared Spectroscopy
Non-invasive monitoring of cerebral tissue oxygenation using near-infrared light absorption.
Full Definition
Cerebral near-infrared spectroscopy is a non-invasive monitoring technique that measures regional cerebral oxygen saturation by analyzing the absorption of near-infrared light by cerebral tissues. The technology provides real-time assessment of the balance between cerebral oxygen supply and consumption, making it valuable during cardiac surgery where cerebral perfusion may be compromised. NIRS monitoring is particularly important during procedures involving circulatory arrest, selective cerebral perfusion, or when significant hemodynamic changes are anticipated. The technique helps guide interventions to optimize cerebral protection.
Usage
Usage note: Often abbreviated as NIRS; distinguish from other oximetry monitoring methods.
