Cerebral Monitoring

Cerebral Monitoring. CEREBRAL FUNCTION MONITORING Introduction and Definitions • The term amplitude integrated electroencephalography (aEEG) is used to denote a method for electrocortical monitoring whereas cerebral function monitoring (CFM) is used to refer to specific equipment aEEG • aEEG is derived from a reduced EEG usually from a pair of biparietal electrodes or two channels from four electrodes one channel from each hemisphere File Size 1MBPage Count 9.

Cerebral oximeters are noninvasive continuous monitoring devices used to monitor adequate cerebral oxygenation They utilize similar physical principles to pulse oximeters The first commercially available cerebral oximeters were used in the 1990s however Jobsis 2 first introduced the concept of using nearinfrared spectroscopy (NIRS) to measure cerebral oxygenation in 1977.

Cerebral Function Monitoring of Neonates

Cerebral Function Monitoring (CFM) should routinely be used for all infants of gestational age ≥ 35 weeks who have one or more of the following a) Evidence of encephalopathy b) Evidence of perinatal distress suggestive of possible hypoxicischaemic encephalopathy (HIE) and who required admission to NICU File Size 1MBPage Count 22.

CEREBRAL FUNCTION MONITORING

Regional cerebral perfusion monitoring Brain tissue partial oxygen tension monitoring (PbtO2) invasive catheter measures oxygenation in very localized area of the brain catheter (probe) need guidance to help place into areas of brain by xenon computed tomography or singlephoton emission computed tomography ischaemia threshold SjvO2 50% = PbtO2 8 mmHg.
