Abstract
The principle of near infrared spectroscopy (NIRS) was first clearly defined by Jobsis in 1977, and recent technical and methodological advances have made it possible to use NIRS to make non-invasive, quantitative measurements of tissue oxygenation and haemodynamics (Reynolds et al 1988). The NIRS technique has been applied predominantly to the measurement of neonatal cerebral haemodynamics (Brazy et al 1985, 1986, Ferrari et al 1986, Wyatt et al 1986, 1991); in particular the quantification of cerebral blood volume (Wyatt et al 1990) and blood flow (CBF)(Edwards et al 1988a).KeywordsCerebral Blood FlowTransit TimeNewborn InfantPulse OximeterCerebral Blood VolumeThese keywords were added by machine and not by the authors.
