Question

Quizplus · Accepted Answer

Brain death is the total loss of brain function, including the brainstem. This can be reliably shown by a flat (or isoelectric) tracing on an electroencephalogram (EEG), which measures brain activity. An electrocardiogram (ECG) measures heart activity, so it is not useful in determining brain death. A CT scan and echocardiograph also do not measure brain activity and cannot reliably determine brain death.
