17 Relationship Between Cerebral Oxygen Delivery, Cerebral Metabolic Rate and the Mean Cerebral Oxygen Saturation in Preterm Infants

BACKGROUND Ensuring the adequacy of cerebral oxygen delivery to meet metabolic demand is important in the brain orientated care of newborn infants. Spatially resolved near-infrared spectroscopy (SRS) is an opt...

The Noninvasive Measurement of Absolute Cerebral Deoxyhemoglobin Concentration and Mean Optical Path Length in the Neonatal Brain by Second Derivative Near Infrared Spectroscopy

We have used second differential near infrared spectroscopy of water to determine the mean optical path length of the neonatal brain. By obtaining the ratio of the second differential features of deoxyhemoglob...

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...

56 RELATION BETWEEN CEREBRAL HAEMODYNAMICS AND OUTCOME IN BIRTH ASPHYXIATED NEWBORN INFANTS STUDIED BY NEAR INFRARED SPECTROSCOPY (NIRS)

The purpose of this study was to measure cerebral blood flow (CBF), cerebral blood volume (CBV) and its response to changes in arterial carbon dioxide tension (CBVR) by NIRS in 21 term newborn infants who had ...
