Near death is often associated with spiritual experiences that are full of mystery and senselessness. In fact, however, this is not always the case. There are several medical and scientific reasons behind near death.
Near death is a phenomenon when a person comes back to life after being declared dead within a certain period of time. Although classified as very rare, this phenomenon is not something foreign in the medical world.
NDE Phenomenon from Medical Review
In medical terms, near death events are often equated with Lazarus syndrome or the Lazarus phenomenon, i.e. the condition of the return of cardiac and respiratory function that had stopped (return of spontaneous circulation) after cardiopulmonary resuscitation or CPR is discontinued.
CPR action is usually performed on people who experience cardiac arrest, coma, or can not breathe spontaneously.
Usually people who experience near death will come back "alive" after being declared dead in about 10 to 30 minutes. However, in very rare cases, there are also people who can come back to life within hours of being declared dead.
Apart from Lazarus syndrome, suspended animation is also often associated with near-death experiences near death experience (NDE). This critical condition will put a person in a coma, difficult to breathe, or even so weak that at first glance it looks like he has died.
However, when his condition improves, he will be able to breathe again, move, wake up from the coma, and his heartbeat will return to strength. This is what is often considered a near death experience.
Causes Someone Can Experience NDE
Medically, doctors can declare that someone has died when they show some of the following signs of death:
- Breath stopped
- There is no body movement and the muscles appear stiff or weak
- No pulse and heartbeat
- Eyelids partially or completely closed
- Pupils are dilated and unreactive to light or touch
- No response to pain, for example when pinched
In addition, when he died, the electrical activity of his heart also disappeared. This can be seen from the appearance of straight lines on the ECG monitor screen.
People who experience near death will show some of the signs of death above, then come back from time to time. Although the cause is not clearly known, there are several factors that are thought to cause the near death phenomenon, namely:
1. Air is trapped in the lungs
When experiencing cardiac arrest, coma, or respiratory failure, a person needs to get help in the form of CPR immediately.
Although it plays an important role in helping the function of the heart and lungs to return to work, a number of studies suggest that this action can sometimes cause a buildup of air in the chest cavity and lungs. This makes it seem as if circulation and blood flow have stopped.
However, after CPR is stopped for a short period of time, this increased air pressure can slowly decrease, allowing the patient's blood flow and breathing to return to normal.
This condition is usually seen when patients receiving CPR can return to show body responses, such as awakening, breathing spontaneously, coughing, or being able to move again.
2. Hypothermia
Hypothermia can cause disturbances in organ function and nervous activity in the body, causing sufferers to experience a decrease in heart rate, pulse, and breathing. This condition occurs because the body is exposed to temperatures that are too cold for a certain period of time.
In some cases, hypothermia can make a person's condition so weak, so that vital signs, such as heart rate, pulse, and breathing cannot be detected. This seems to indicate that he has died.
However, when he gets medical attention as soon as possible and his body temperature returns to normal, blood flow and the functions of various organs in his body will return to work so that it returns to "life". This phenomenon is often regarded as suspended animation.
3. Hyperkalemia
Hyperkalemia is a condition when the amount of potassium electrolyte increases too high. This condition can make the function of the heart, lungs, and nerves and brain disrupted. If left untreated, this condition can cause a person to experience cardiac arrest and coma, making it appear as if he died.
The incident of near death in the medical world can indeed happen. Therefore, before declaring the patient dead, doctors and medical staff will wait and monitor him for about 10-15 minutes after stopping the CPR procedure.
If indeed there is no change and the patient still shows signs of death, the new doctor will declare that the patient has died.
So, in conclusion, the near death phenomenon is not caused by things that smell paranormal or mystical, yes. If you still have questions about near death, you can consult a doctor for a more complete explanation and information.
