Brain Oxygenation Monitoring

Brain Oxygenation Monitoring.

A mismatch between cerebral oxygen supply and demand can lead to cerebral hypoxia/ischemia and deleterious outcomes. Cerebral oxygenation monitoring is an important aspect of multimodality neuromonitoring. It is increasingly deployed whenever intracranial pressure monitoring is indicated. Although there is a large body of evidence demonstrating an association between cerebral hypoxia/ischemia a...

Monitoring Oxygenation

The most basic goal of anaesthetists and intensivists is to assure that there is an adequate supply of oxygen to the mitochondria throughout the body to maintain aerobic metabolism and cellular function. The determination of adequate oxygenation has historically been monitored by the absence of organ dysfunction because techniques were not available to assess quantitatively the oxygenation of t...

Near infrared cerebral oxygenation monitoring

This technique employs principles of optical spectrophotometry which exploits the fact that biological material including skull, is relatively transparent in the near infrared range. Light transmission depends on a combination of reflectance, scattering and absorption effects. Reflectance is primarily a function of the angle of the light beam to the tissue surface, while scattering decreases wi...
