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...
متن کاملMonitoring Cerebral Oxygenation in Neonates: An Update
Cerebral oxygenation is not always reflected by systemic arterial oxygenation. Therefore, regional cerebral oxygen saturation (rScO2) monitoring with near-infrared spectroscopy (NIRS) is of added value in neonatal intensive care. rScO2 represents oxygen supply to the brain, while cerebral fractional tissue oxygen extraction, which is the ratio between rScO2 and systemic arterial oxygen saturati...

متن کاملMonitoring cerebral perfusion and oxygenation: an elusive goal.
The impetus for cerebral hemodynamic monitoring in neurotrauma first arose from the original "talk and die" studies which described the group of head injured patients "who talk and then subsequently died". At necropsy, hypoxic or ischaemic brain damage was observed in a variable proportion of patients raising the possibility that systemic or cerebral hypoxia post trauma may have contributed to ...
متن کاملMonitoring cerebral oxygenation during balloon occlusion with multichannel NIRS
We report on oxygenation changes noninvasively recorded by multichannel continuous-wave near infrared spectroscopy (CW-NIRS) during endovascular neuroradiologic interventions requiring temporary balloon occlusion of arteries supplying the cerebral circulation. Digital subtraction angiography (DSA) provides reference data on the site, timing, and effectiveness of the flow stagnation as well as o...
