Predicting Oscillation in Arterial Saturation from Cardiorespiratory Variables
The potential of near infrared spectroscopy (NIRS) as a non invasive tissue oxygenation monitor was first outlined by Jöbsis (Jöbsis, 1977). Extension of the basic technique to measure tissue blood flow using ...

Continuous Measurement of Cerebral Oxygenation by Nirs During Induction of Anaesthesia
Continuous intraoperative monitoring of cerebral oxygenation is not routine because existing techniques are either invasive, require a prolonged period of equilibration or involve the use of ionizing radiation...

Delayed (“Secondary”) Cerebral Energy Failure after Acute Hypoxia-Ischemia in the Newborn Piglet: Continuous 48-Hour Studies by Phosphorus Magnetic Resonance Spectroscopy
ABSTRACT: Phosphorus (31P) spectra from the brains of severely birth-asphyxiated human infants are commonly normal on the first day of life. Later, cerebral energy failure develops, which carries a serious progno...

Investigation of the Effects of Hypocapnia upon Cerebral Haemodynamics in Normal Volunteers and Anaesthetised Subjects by near Infrared Spectroscopy (NIRS)
The effect of alterations in arterial carbon dioxide tension (PaCO2) upon the cerebral blood vessels was first described in 1930 by Wolff and Lennox and quantified in 1948 by Kety and Schmidt. Since then many stu...

Chapter
An Automated System for the Measurement of the Response of Cerebral Blood Volume and Cerebral Blood Flow to Changes in Arterial Carbon Dioxide Tension Using Near Infrared Spectroscopy
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 oxygenation of intact organs and to date...

Chapter
Measurement of Changes in Cerebral Haemodynamics During Inspiration and Expiration Using Near Infrared Spectroscopy
Near infrared spectroscopy (NIRS) has been employed over the last decade to monitor the changes in tissue oxygenation of intact organs (Jobsis 1977, Brazy et al. 1985, 1986, Ferrari et al. 1986a, 1986b, Hampso...

Chapter
Measurement of Adult Cerebral Haemodynamics Using Near Infrared Spectroscopy
Near infrared spectroscopy (NIRS) is a non invasive, portable, safe technique for monitoring cerebral oxygenation and haemodynamics. Since it does not involve the use of ionising radiation it may be used repea...

EFFECT OF MASK VENTILATION ON CEREBRAL BLOOD VOLUME (CBV) IN PRETERM INFANTS STUDIED BY NEAR INFRARED SPECTROSCOPY (NIRS)
Mask ventilation has been reported to cause cerebral haemorrhage in preterm infants, possibly due to head compression. We used NIRS (1) to measure the effect of mask ventilation on CBV in 8 preterm infants bor...
