Can we bring a dead person back to life after death? To test this, in the early 1900s, some

experiments were conducted on dogs that would shake the heart of any ordinary person. Take

a look at this clip. This is not a living dog, but a dead dog whose severed head is connected to a

machine that copies the heart and lungs.

Now, in this scene, as soon as the scientist puts citric acid on the dead dog's face, it starts

licking it. But this was not the only proof of responsiveness in the dead dog. When a light is

turned on in his eyes or a table is knocked with a hammer nearby, he responds to those

stimuluses too, which just proves that the dog was not only biologically alive, but was also

conscious about what was happening around him.

But now the question arises, how? I mean, apart from the brain, heart and lungs, the proper

functioning of other organs is also important for survival. So how was a dead dog brought back

to life And has any such experiment ever been tried on humans? If yes, then what happened to

them? Well, today we will learn in detail about these scientific experiments on the revival of

dead. Because, you know, there are many such cases in our society.

For example, just a few days ago, an open-armed girl was murdered in a Bangalore PG.

Sometimes someone is killed in the middle of the road and the spectators get confused as to

what to do. Some people do not take action, thinking that someone else will take it.

Till then I wait. Or someone thinks that what is the use of taking action when the person is

already going to die. So in such a situation, how much time does a person have to save the life

of the victim and to get him out of the mouth of death or to be able to bring him back to life

even after death? Well, very soon you will have answers to these questions.

And with that, from today's video, you will also learn some very important life-saving skills

which can be very useful for you in emergency situations. So the fear of death is the ultimate

fear for any human being. And interestingly, the experiments that brought a person back to life

after death were even scarier than the experiments in which scientists performed them.

Today, in the age of human and animal rights, no one can even think of performing them. So

then, what was so special about the era 100 years ago that scientists were not thinking twice

about performing these cruel experiments? So all this begins in the decade of 1914-1923, which

was called the most bloody era in the history of Soviet Russia. So much so that this entire

decade is still called the reign of death in Russia.

In these 9-10 years, the time of the Soviets was so bad that whatever step they took for the

benefit of their country, it would take the turn of destruction and the lives of millions of people

would be lost. First of all, in 1914, the countries situated on their western border, Austria-

Hungary and Serbia, become the centers of World War I. Because of which Russia is also

dragged into that war and 2-3 million soldiers are killed. But this was just the beginning.

Because after that, between 1918-1921, a civil war starts all over the country, in which mass

migrations occur, epidemics spread, and again, around 8-10 million people are killed. And after

all this, when the wars finally end, and peace seems to be established in the country, it seems

that the year 1921 suddenly becomes dry and again, millions of people are killed. All in all, it is

said that in this sequence of events, between 1914-1923, around 15-20 million Russians died

before time.

Now, how do we make up for all these deaths? So well, the new Soviet government that was

formed in those days, immediately implemented a new economic policy in the country, due to

which people's condition began to improve, and they were able to leave their trauma behind

and move on in their lives. Except one group, Soviet scientists. After looking at death so closely,

Soviet scientists were obsessed with death.

Like literally, from the early 1920s, the books, brochures, pamphlets, or even articles they

published, just look at their titles. Life and Death, What is Death? Death from the Point of View

of Modern Science, Aging and Death, The Problems of Death and Immortality, Death and

Revival, The Enigma of Death, and so on. In fact, you won't believe it, in 1924, a renowned

pathologist, Georgil Shor, suggested that there should be a separate special field in science,

which should deal only with death.

And in the name of Greek God of Death, Thanatos, he also suggested the name of that scientific

field. Thanatology. You can see, they desperately wanted to understand death.

What exactly is death in proper medical terms? Now, Soviet scientists, who were part of the

early race, quickly became scientists of other countries. And now, they not only wanted to

understand death on a theoretical level, but also practically. And in that era, there were two

scientists, who were ready to go to any extent, to bring a dead person back to life.

The first name was Soviet scientist, Sergei Brukhonenko. And the second name was American

scientist, Robert Cornish. Now, specifically, Robert Cornish, is still known as a mad scientist.

Because, at that time, with the help of a giant seesaw, he was trying to bring the dead back to

life. So, what did Cornish do? Well, he would tie a human body to a seesaw-like tether, Then, he

would inject blood-thinning chemicals like adrenaline and heparin. And then, he would move

the tether up and down, and with the help of gravity, he would try to circulate blood all over the

body.

His idea behind this was, that oxygen would come in through the mouth and nose, and then, it

would be found in the blood, and then, it would start circulating all over the body, which could

bring the dead back to life. So now, the million dollar question, did the dead come back to life?

Well, as you can imagine, not a single dead came back to life. But, according to Cornish, it was

the dead who were at fault.

No, I am serious. Cornish believed that, it had been a long time since the dead had died, and

that's why this method didn't work on them. But, if this experiment was done on freshly dead

humans, then it could work.

So, Cornish again, tried the same experiment on 5 freshly dead dogs, who were named Lazarus

1, 2, 3, 4, and 5 respectively. The first 3 of them, as expected, died on Tetherbolt. Which means,

they died, but surprisingly, the last 2 came back to life.

Which means, Cornish was not that mad, after all. And what could be the science behind this?

We will talk about this later, because this experiment, according to the modern science, would

definitely seem silly to you. But, did Cornish, even though unknowingly, crack any code to revive

the dead body? Well, to know the answers to these questions, we have to shift from the USA to

the USSR.

Because there, Soviet scientist Sergei Brukhonen was also going to extreme lengths to revive

the dead. But, unlike Cornish, his method, according to today's standards, was a little more

scientific. So much so, that in today's modern open-heart surgeries, to keep the patients alive,

the artificial life support system they are connected to, is believed to be inspired by his

experiments.

Actually, on 18th September 1925, Sergei Brukhonen brought a very interesting invention to

the world. When he was giving a conference to all the big medical professionals in Russia, he

presented a device called an autojector, which could mimic the function of our heart and lungs.

It basically had 2 electric pumps, which were connected through rubber tubes to the main veins

in the throat.

And on the other side, these 2 pumps were connected to an oxygenation vessel, where oxygen

was added to the blood. Basically, through this device, Brukhonen's idea was that a pump

would draw deoxygenated blood from the dead body and send it to the oxygenation vessel.

And then, after oxygen was added to it, the second pump would inject that oxygenated blood

back into the body.

And in this way, a dead animal could come back to life. Now, in the beginning, the experiment

of the head-cutting dog I showed you, was actually a live demo of the same thing, which

Brukhonen had publicly shown. And this was proof that Brukhonen's method worked and it was

better than Cornish.

But, unfortunately, the dogs whose heads he had revived could only survive for 1 hour and 40

minutes. So, Brukhonen found out that he had to make his technique even more fool-proof.

And that's why, in such a situation, do you know what his next demonstration would have

been? Well, this time, he took a whole dog, then cut the main vein in its neck and extracted all

its blood so that the dog would die.

Then, he waited for about 10 minutes so that there was no chance that it was alive. And then,

finally, after 10 minutes of death, he connected the dead body to the auto-jector and tried to

revive it again. And then, look at this footage.

This is the same dog on which the experiment was done. As you can see, it has completely

recovered. As if it had never died.

Which means, he literally killed a patient and revived it. Now, obviously, after this success, you

will definitely ask, did Brukhonen ever try this on humans? Well, I tried to find a lot in academic

records, but personally, I did not find any documented proof of this. But, one thing is absolutely

clear from this experiment that if blood and oxygen are supplied to a dead body in the right

amount within a 10-minute time window, then it can be revived.

But, just think, why was the dog kept dead for just 10 minutes? Why not more than that? And

you must have seen the same thing in movies, in which, many times, doctors say that if the

patient had been brought in just 10 minutes earlier, then his life could have been saved. Plus,

you must have also seen many times that if someone is dying and there is a straight line on the

ECG monitor, then the doctor immediately takes out an injection and applies it and then later,

by giving a shock, tries to revive the victim. So, is 10 minutes the final limit after which no one

can be revived So, well, to answer this question, we must first understand the process of death.

Death is not a one-point event, but a process in which there are some stages through which the

body goes through. Even if a person's consciousness goes into a shock, he becomes

unconscious, but while dying, every body goes through the process of death. So, look, when a

person is dying, especially in an unnatural way, like an accident, then the body goes through

four major stages.

The first is shock. If there was an accident, someone fell from a height, someone shot someone,

or even if someone died hanging from a fan, in any case, that initial trauma, if it causes

significant blood loss or in the case of hanging from a fan, severely restricts blood flow or

damages the organ, then in such a case, the body goes into a shock state In this state, the body

tries to somehow reach the heart, lungs, and brain, these three mitral organs, at least

somehow, to deliver blood. And that's why, at such a time, the pulse rate of the victim

increases, BP drops, and non-vital organs start to feel pale and cold, because the blood there

has been diverted.

Now, this is a very crucial stage, because at this stage, if you have somehow controlled the

bleeding, let's say, by covering the bleeding spot with a thick towel and applying pressure, then

you can delay the victim's death for many hours. And that's why, if an accidental victim has

heavy bleeding in front of you, in any case, you can try to stop the blood loss first. But let's say,

there is a lot of bleeding, and the victim's body has become kind of swollen, and blood is

leaking from everywhere, then what will happen? Well, in that case, the victim moves towards

the second stage, which is called hypovolemic shock stage.

Basically, when the bleeding becomes too much, there is not enough blood left in the veins to

cover the organs with sufficient pressure. And that's why, the organs stop getting oxygen. In

this situation, you will see, the victim looks weak and confused and then, his breathing

becomes very fast and then, finally, he becomes unconscious.

Now, after this stage, most of the time, you cannot save a person from death at your level. And

at this level, most of the accident victims also die. But actually, this can be stopped to a great

extent.

If only one thing can be done, which we will talk about in a while. Look, at this level, a person

can only survive in a hospital or medical facility because he can only externally supply extra

blood and oxygen. If this happens, the patient's death can be delayed for some time and he can

be from that critical R. But if this doesn't happen, then the cells of all the patient's organs will

due to lack of blood and oxygen.

And in this situation, the patient will reach the third stage of death which is called clinical death.

Basically, is that, if the heart stops and the breathing also stops, then there is no pulse and the

monitor also shows a straight line like this. And that's why this stage is technically called clinical

death when the heartbeat has stopped.

Now, the dog in Brukhonenko's experiments, was actually brought back from the same type of

death. In this stage, in most cases, the doctors have around 10 minutes to kick start the

heartbeat of the victim again. But if this doesn't happen, unfortunately, then the patient enters

the final stage of dying which is called biological death or even brain death.

In this stage, because the brain didn't get oxygen for several minutes, the cells of the brain and

other organs start dying very fast. And the control of our body and organs starts getting lost.

And that's why you will see, in this last stage, the victim's eyes get fixed on one thing and the

pupils of the eyes get dilated or spread.

And unfortunately, this is the final stage of death after which nothing can be Millions of cells

have literally died. They can't be revived with any medical procedure. Just like a broken glass

can't in the same structure again.

Sometimes, it happens that after a clinical death, while reviving the patient, the patient gets

revived but to some extent, his brain cells would have And because of this, either the patient

goes partially into a coma or becomes just a living corpse. I mean, just think about it. His heart

is working, he is breathing and maybe other organs are working but his brain is dead.

His brain cells are literally dead. He can't see anything, he can't hear anything and he can't even

feel anything. Just a living corpse, with a beating heart.

Just like cardiac arrest patient Carol's case, her heart beat stopped completely due to cardiac

Meaning, the clinical death had already happened but after 45 minutes, she was revived again.

Here, the 10-minute limit was far exceeded and revived after 45 minutes. Dr. Sam Pernia, who is

the Stony Brook University in New York, according to him, Carol is not the only person like this.

There are many patients who were able to revive after a few hours after death. Basically, to

revive a technique is used called defibrillation. The person experiencing clinical death means

the person whose heart is losing its natural rhythm and stopping, is given a shock and revived.

You must have movies as well. In this, basically, there is a defibrillator machine in which two

pads are touched the chest region of the patient and then the charge is released. Ideally, in the

first shock, the patient's heart should restart and start beating with normal heartbeat.

But if this does not happen, two more attempts are done. Epinephrine or vasopressin are given

to constrict the nerves and increase the BP so that the heart muscles get more oxygen and can

kick start in normal rhythm again. One very important thing is that if the CPR is given to the

then the chances of the person being revived drastically increase with this CPR is basically a

technique in which the chest of the patient is mechanically pumped with blood from the You

can watch this video in which you will its basic science.

I have put the link in the description below. This technique is also very important for everyone

because it can be emergencies such as heart attacks or drowning cases. In the case of CPR was

also given so that she after 45 minutes.

Anyway, now we have talked about but what can we learn and how can we make this world

better? As you know, we want to bring personal and social empowerment through science and

want to thing without a doubt that science is not just a subject but a thought. The thought of

progress is of a better life and society. So when an accident happens in or someone gets

injured how soon should we take the victim to the hospital? In such situations, we get confused,

right? Should we take her to quickly or should we wait for the ambulance? So what should we

do here? For this, you have to in a very short time as to how much time can be saved.

In medical field, there is a concept called Trimodal Distribution of Trauma Deaths. In this, it can

be basis of where the been injured and how much time they have. The first category here is of

Immediate Deaths.

That is, a person can die in just a few minutes. And most of the time, in such cases, there is no

chance that the patient can reach the hospital alive. There are some other cases where there

can be immediate death which you can see on The second category is of Early Deaths.

That is, those victims who can die in a few minutes to few hours. In this category, there are

those people who have abdominal injuries or fluid accumulation in the lungs or moderate

bleeding throughout the body. There are some other cases which you can see In these cases,

with adequate first aid help, a victim can easily spend a few hours before dying.

Now, what they call Deaths. Such deaths are mostly rare and often happen after a few days or

weeks. Mainly, near the injury site or it remains unnoticed, it can lead to complications in the

future.

Now, why is it that most of the patients die in this golden hour and how can they be saved? In

this context, the condition in India is even worse. Our statistics show that 50% road accident

deaths happen only because the victim does not get the necessary medical care in the first Do

you know the reason for Recently, when AIIMS and Neeti Aayog together assessed the

emergency medical services of the entire it was found that 90% of India's road ambulances do

not have the necessary medical equipment. 95% ambulances are operated by untrained staff

and almost 98.5% ambulances do not deliver patients but only the dead.

Now, in most developed countries, ambulances have trained medical staff and all the necessary

medical amenities are also available. With their help, these staff can easily kick-start the blood

circulation of the victim and even to the hospital through oxygen masks. The most in this

golden hour is oxygen and blood, which can drastically delay the and increase the chances of

the patient But, unfortunately, these facilities are not available in most of the ambulances and

many people are not even informed that they can opt willingly.

In Indian cities, the traffic is so heavy that it takes half an hour to reach Literally, in this most

Can We Bring the Dead Back to Life?

important moment, it will be like a patient's life. So, in critical situations, we should always

confirm and opt for an advanced life support ambulance in which all the life support facilities

are present. Through this video, I would also like to appeal to the medical and governmental

authorities According to the data, it is absolutely clear that due to the absence of proper

ambulance facilities, 98.5% medical emergency ambulances are only able to take the dead to

the hospital.

We need a lot of advancement and improvement here. And finally, friends, if God doesn't want

us to die, but there is an accident, then please take action as soon as possible. Don't wait for

someone else to take it.

You know very well how important the golden hour is for any victim. If you feel that the

ambulance is going to take a long time to reach and the hospital is nearby, then you can

directly get to the emergency ward of the Every minute here is extremely precious, just like the

life of a person. With that said, thank you for watching this science video till the end.
