Abstract

The brain is extremely vulnerable to ischemia due to its high metabolic demand and reliance on cerebral blood flow (CBF) for a continuous supply of oxygen and glucose. This vulnerability is a major focus of intensive care management of adult patients with neurological emergencies and critically ill newborns. And it has led to the search for suitable bedside monitoring technologies to assist the intensivist team identify critical perfusion levels before brain injury occurs. Near-infrared spectroscopy has long been considered ideal for neuromonitoring because the technology is noninvasive, safe, and portable. This chapter will present the methodology and application of one NIRS approach, based on tracer kinetic modeling, for quantifying cerebral hemodynamics and energy metabolism.

Key words
