What is the most reliable diagnostic examination for brain death?

Question

Quizplus · Accepted Answer

The most reliable diagnostic examination for brain death is the apnea test. It is used to determine if there is any breathing activity in the patient, which is a crucial component of brain function. The test involves removing the patient's breathing support for a period of time and observing if there is any respiratory effort. If there is none, it indicates that the brainstem, which controls breathing, is no longer functioning, and therefore, brain death has occurred. Other diagnostic examinations, such as neuroimaging, oculocephalic reflex, and pupil dilation, are supportive tests that can help confirm brain death but are not as reliable as the apnea test.
