Abstract Near Infra-red Spectroscopy (NIRS) has been widely used to study intracerebral
oxygenation and haemodynamics in neonates (1, 2), but doubts have been raised over the …

Since its development by Jobsisi Near Infra-red Spectroscopy (NIRS) nas been used to
study cerebral oxygenation non-invasively in both neonates 2, 3 and more recently in adults …

The use of optical spectroscopy for the non-invasive monitoring of tissue oxygenation and
metabolism is well established (Chance et al., 1975). Historically because of the high …

The technique of near infrared spectroscopy (NIRS) is being increasingly used in clinical
measurements of blood and tissue oxygenation (Wyatt et al 1986, Edwards et al 1990). and …

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 …

Abstract Theoretically, Near Infrared Spectroscopy (NIRS) can be used as a non-invasive
and fast method to quantify cerebral blood flow (CBF) in neonates (Wyatt et al., 1990) and …

The first clinical application of near-infrared spectroscopy (NIRS) 11 years ago was on the
head of newborn infants under intensive care. Since then much credible and some important …

NIRS in transmission mode has been shown to provide useful information on intra cerebral
oxygenation in neonates 1, 2, and is beginning to be applied to adults using reflectance …

Adult near infrared spectroscopy (NIRS) is a potential method for noninvasively assessing
changes in cerebral oxygenation. Unlike neonatal NIRS, access of light to the adult brain …

Since it was first described by Jobsis in 1977, near infrared spectroscopy (NIRS) has
become widely used as a non invasive technique for monitoring the blood and tissue …
