Medicine has to conduct rational scientific analysis and demonstration on this. After many medical experts' research, the medical community has reached a consensus. After the machine is removed, the patients whose spontaneous breathing and heartbeat cannot be restored are because the most important part of the brain, the brainstem, has died and cannot be reversed by medical means, so it is called brain death.
Medical scientists have discovered that lack of blood and oxygen can lead to brain death. If rescued in time, the brain can be re-perfused with blood and nutrients within a certain period of time, and it is possible to restore function and avoid brain death.
In summary, there is a time lag for brain death. It is true that the machine is used to save brain cells during rescue. If the machine is used for a long time but the patient cannot recover his or her spontaneous breathing and heartbeat, it means that the brain is dead, and the person is dead anyway.
The debate on brain death comes back to how long this time difference is. The length of this time difference is the reason why various opinions in society collide. If you cannot scientifically determine the length of this time difference for a specific individual, you may misjudge the patient's death.
Some big data in statistics cannot be specifically classified to individuals. For some people, this time difference is longer, and for others, it is shorter. Don't underestimate the time difference of one minute or one second, which can really determine life or death.
To have sufficient factual evidence of brain death, we must go back to the beginning. Doctors must find evidence to prove that the patient's brain is dead, rather than just looking at the time.
In the past, neurologists were specialized in this area and were the most qualified to find evidence to determine whether a patient was brain dead. The problem is that the problem of insufficient clinical manpower is too common. In order to make up for the inconvenience of insufficient manpower and other problems, the international practice is to set a standard for determining brain death, which does not require specialists but only clinical doctors, who can be competent after short-term training and passing a qualification exam.
At this point, some people may doubt whether non-neurologists can determine brain death.
There is no need to be nervous about this issue. In fact, the determination of brain death is a process, just like the determination of cardiac death. There is a rule in the criteria for determining brain death: the cause of the patient's illness must be clearly identified, and it must be clear that it is irreversible brain damage that leads to brain death.

This stage requires the in-depth involvement of neurosurgeons and cannot be ruled out.
At this point, we can understand why Cao Yong insisted on sending his child to a specialist hospital like Fangze. Obviously, he wanted to prevent omissions from happening in all aspects. With the most professional team of neurologists, they can do their utmost to avoid misdiagnosis of the child's condition due to medical inaccuracy.
This answered some of Cao Zhao's doubts, and at the same time, he heard an answer from his brother's words that he wanted but didn't want: "You think the child was already brain dead at the time, right?"
"I was at the scene. What other tools did I have on hand except a flashlight and cotton swabs?" Cao Yong found it funny.
Didn't he say at the beginning? Medical diagnosis is a very, very rigorous matter. Although he is a doctor, he doesn't have X-ray vision, so how can he see what the child's brain injury is?
"We need to do a CT scan, and more than once." Cao Yong emphasized the key point he had made.
Don't take the final result as what their uncle revealed on the phone, that the preliminary CT scan showed that the child had brain stem damage.
