Amplitude integrated electroencephalography
Amplitude integrated electroencephalography (aEEG) or cerebral function monitoring (CFM) is a technique for monitoring brain function in intensive care settings over longer periods of time than the traditional eletroencephalogram (EEG), typically hours to days. By placing electrodoes on the scalp of the patient, a trace of electrical activity is produced which is then displayed on a semilogarithmic graph of peak-to-peak amplitude over time; amplitude is logarithmic and time is linear. In this way, trends in electrical activity in the cerebral cortex can be interpreted to inform on events such as seizures or suppressed brain activity.[1] aEEG is useful especially in neonatology where it can be used to aid in diagnosis of hypoxic ischemic encephalopathy (HIE), and to monitor and diagnose seizure activity.
