What is the death of the brain?
Death of brain stem is a confirmation of death based on a set of criteria that generally tests reflexes of brain stem. It is assumed that if the brain strain does not respond to these reflexes during the examination, the brain and the body are no longer able to communicate, and therefore the patient has no chance of recovering. As such, the patient is then declared dead. Examination for the death of brain stem deaths is not easy because the patient must pass strict prerequisites before it is considered a test. If the patient goes through, two higher physicians must perform the procedure and the patient must show any reflexes of the brain stem on two separate occasions; This means that they have to pass the test twice.
The diagnosis of the death of the brain stem is three phases. First, the cause of the patient's coma must be known and the physician must also prove that the patient suffers from brain damage that is out of repair. Secondly, the patient must not be in a state in which the Hijs dysfunction of the brain tribes is reversible and could therefore change the results of the examination. For exampleLAD drugs, hypothermia and severe metabolic stir can cause the patient to not respond to stimulating brain stem. Third, the patient cannot show reflexes of brain stem at all in response to the criteria set out in the test.
The test will take less than half an hour long for it to take less time to take the patient for the test. When doctors perform a test, they will look for signs of responses that would normally communicate in response to stimulation. All these criteria must be met to confirm the death of the brain stem.
The first criterion is that the patient's pupils do not interfere in response to direct light that is shined into the eyes. Second, the patient's eyes do not blink in response to corneal stimulation, as if the doctor caresses the cornea with a piece of fabric or tissue. Thirdly, the patient does not respond, such as grimace, when the doctor applies solid pressure, for example directly above the eye socket. Fourth, eyesThe patient does not move how normally, in response to ice water that was rinsed into the ear. Fifth, the patient not cough or gag when the doctor stimulates the back of the neck or passes through the respiratory tract on the airways; In the end, the patient does not bother alone when it is separated from the fan.
