Can a person live without a heartbeat If a person has no heartbeat, is there any salvation? How is i

Death is the termination of life's activities. Generally speaking, it is not difficult to determine whether a person is dead or not, as long as the heartbeat and breathing have completely stopped and can no longer be restored, they can be considered dead. Death in which the heart stops beating first is medically called cardiac death; Death in which breathing stops first is called respiratory death, or lung death.

However, the cessation of breathing and heartbeat does not indicate that it is inevitable to die, such as a patient admitted to Yihua Hospital the year before last suffered from cervical myelitis respiratory muscle paralysis, and his breathing has completely stopped, but with the help of artificial ventilators to assist breathing, and then continue to recover after **. Some people with heart disease can stop their heartbeat completely, but they can also survive with the help of a pacemaker. In some cases, patients with electrical injuries and drowning, even if their breathing and heartbeat have completely stopped, can be saved.

Because after the cessation of blood circulation and breathing, the cerebral cortex usually tolerates hypoxia for 5-6 minutes (but it can be relatively prolonged under low temperature conditions), which is generally referred to as the clinical death period. During this time, it is possible to resuscitate if the rescue is actively carried out; Conversely, beyond this time, irreversible changes will occur in the brain, resulting in a permanent loss of brain function, which is brain death. Brain-dead patients, even though the heartbeat and breathing may be maintained by the resuscitation techniques of modern medicine, the eventual death is inevitable.

So, there are some car accident patients who have severe brain damage, loss of consciousness, and gradual cessation of heartbeat and breathing, but continue to maintain the patient's breathing and heartbeat with artificial ventilators and pacemakers, plus other assistance**, although"Survival"After several days, his sanity never recovered, and as soon as he stopped using the ventilator, he immediately stopped breathing, and his heartbeat stopped one after another, and finally he had to give up resuscitation. If an autopsy is done, it will be found that most of the brain tissue has already died, and a few days of rescue are actually in vain. From brain death, we naturally think of what is commonly referred to as vegetative people, are they the same thing?

No. The fundamental difference between these two concepts is that the former does not breathe spontaneously, while the latter does. The higher neural activities of the vegetative brain, such as thinking, consciousness, intelligence, and orientation, have been lost, but the lower functions such as breathing and digestion are still preserved and can exist for a long time.

From a medical point of view, an accurate diagnosis of brain death not only provides a correct estimate of the possibility of resurrection, but also has important significance for organ transplantation. Because the development of allogeneic organ transplantation requires a large number of organs that can be transplanted, and the fresher the better. Therefore, a person who has been brain dead and still relies on resuscitation to maintain breathing and heartbeat is the best donor for an organ transplant.

However, both the diagnosis of brain death and the administration of organ transplants must be permitted and guaranteed by law, and the wishes of the patient or family should be respected.

Can you live without a heartbeat? Definitely hanged.

Brain death is death, if the brain is alive, everything is still hopeful, if the brain is dead, the body is still permanently vegetative. If you don't have a heartbeat and still breathing, you are not dead, but if you don't send it to the hospital for first aid, you will die, and you can also perform cardiac resuscitation.

If a person does not have a heartbeat, it may still be saved, after all, he is still breathing, so he should be given some cardiopulmonary resuscitation or some artificial respiration as soon as possible. It would still be possible to get the person back.

There is no heart tube beating and there is no help. A heartbeat is the beating of the heart, and there is no way to survive without a heartbeat. The blood of the whole body of the human body needs to be transported to all parts of the body, and fresh blood containing nutrients and oxygen cannot be transported to the whole body without heartbeat, and the tissues and organs of the whole body will fail and cannot function normally.

OK. According to medical regulations, only when the brain is dead can it be declared dead, and when the brain stops, it can be declared dead.

The heart is the organ responsible for supplying blood to the whole body, and the blood is needed by the cells.

of nutrients and oxygen. If the heart stops beating, then the cells are in a state of metabolic stagnation, scientific data says that 8 minutes will not cause much damage to the cells, and 20 minutes the brain cells will slowly start to die due to lack of oxygen, and the whole process will take about an hour.

It can be understood that the heart stops beating, but the cells of the whole body and the brain are not completely dead, but because of the lack of oxygen, the person is in a coma, such as electric shock, drowning... Even if the rescue is not life-threatening (within 20 minutes).

Can you live without a heartbeat? Definitely hanged.

Brain-dead then.

This man must die. But.

The heart stops instantaneously, and if it is rescued in time, it is possible to be rescued. If the heart stops beating for too long, the blood.

in oxygen. If the content is too low, it will lead to a large amount.

Brain cells die due to lack of oxygen. Cause it mildly.

Patient amnesia, bodily functions.

loss and so on, the most serious is caused.

Brain death. So, after the heart stops beating, the brain can survive for a while, but only for a short time.

One. Cardiac Arrest Limit: About 4 Hours According to a report by Shanghai Family Daily, medical theory holds that under normal circumstances, after 4 minutes of heartbeat, the human body may die due to the inability of the brain to obtain blood and oxygen.

Two. Heart rate limit: 220 beats in 1 minute Heart rate limit refers to the heart movement limit, which refers to the number of heartbeats that the heart can work to the maximum limit that has been scientifically discovered so far, that is, the calculation formula of the maximum heart rate of the human body.

Beyond this value, the heart will not be able to continue to perform its normal blood beats. Even when participating in physical activity, it is impossible to exceed this limit when it comes to detecting and evaluating the effects of exercise. Extreme sports are the same as facing emergencies, if a person is constantly in a state of emergency combat, the body will feel particularly weak as soon as the process is over.

In the long run, life will be overdrawn. 2.5 billion to 3 billion heartbeats in a lifetime Scientists have found that a tortoise can live up to 177 years because it has a heart that beats only 6 times per minute and about 100 million beats in a lifetime. Amazingly, with the exception of humans, all mammals have basically the same number of heartbeats in their lifetime, about 100 million beats, while the total number of heartbeats in a human lifetime is about 2.5 billion to 3 billion beats.
