Death of our loved one is a disaster for us, particularly if it is premature and unexpected death. As we noted the birth date and time, we also note death date and time of our loved one but are we able to note the right time of death?

Actually, we are dependent on doctors if our loved one is dying(Nearer to death) in a hospital bed.

  • Are they telling us true?
  • Is it possible to know the exact time of death like birth?
  • The death timing which mentioned on the death certificate by the hospital, is that correct timing of death?
  • Is there any life after death?

If you want to find the answer to the above questions then carefully go throw this article.

What is death

Death is the permanent cessation of body functions which is necessary for life, it simply means the end of life. But there is a problem in the definition that, actually life lives in which part of the body?

There are three types of death in medical sciences 1. Brain Death 2. Clinical death 3. Biological death

Brain Death

Brain death is the complete and irreversible loss of brain function including involuntary activities. This differs from a coma and vegetative state but in this stage, a person is alive on mechanical ventilation and other life supports. There are some autonomic functions remains like activity of the heart(Heart cell does not require brain impulse to function, its specialized cells have its own impulse)

It differs from the coma and other disorders. The person never ever waking up because of irreversible brain damage, the person is just like a dead body. It is considered a legal death in some country.

You can easily know the difference in EEG(Electroencephalography) and by Cerebral angiography.

What if my loved one is having brain death? What should I do?

The bitter truth is your loved one never gonna wake up, but his vital organ like kidney, heart, liver are still working, because the heart is pumping blood to this organs. If you want to do something then donate the organs of your loved one, by doing this you can possibly save 108 lives.

“Braindead” means the person is legally dead, but if you want to keep your loved one’s body alive you can do it by some life support equipment and ventilator. But in some countries law, a brain dead person automatic become an organ donor.

Clinical death

It means cessation of blood circulation and breathing.

When Heart stop beating(Cardiac arrest) then the blood circulation stops in the body. After a few seconds person starts gasping and becomes unconscious. Within 20 to 40-seconds major brain functions stop due to lack of oxygen in the brain and in 4 to 6-minute brain cells start dying. But, in advance medical practice cardiac arrest is reversible by CPR(Cardio Pulmonary Resuscitation), Defibrillator and epinephrine.

Clinical death is the word which is mentioned in the Death certificate and Death report. But you cannot say perfect timing of death and After clinical death also the person is not biologically dead and can still donate the organs.

Doctors in the hospital only confirm the clinical death, when their team is tired of giving CPR and there is a very low chance of survival. But I want to say that the time mentioned in the medical record is only when the doctor confirms the death, the person died before confirmation(Here the meaning of died means There is no electrical activity in the heart and no brain activity). In another way, there is also a negligible chance of survival after confirmation of clinical death and it also practically possible. So, the time of death of your relatives you depends on doctors when they decided to confirm. Always take care of the body may be still life is remaining in the body.

Biological death

It is the death in the cellular and molecular level, mean the cells individually died(when you say heart died there may be some cells in the heart still alive but in biological death, there is the death of every cell). But no one waits till biological death or no one tries also because after clinical death the patient is declared dead.

Is there any life after Death

In other words, death is an irreversible cessation of all functions of the body and it erases the existence of someone from the world. But, you know that there are many organs that can be transplanted from one dead body to another human being who is alive.

Advance definition of death said that the irreversible cessation of all vital functions especially as indicated by the permanent stoppage of the heart(Circulation), Lung(Respiration), and brain activity is death, But there is another problem that CPR and Some advance drugs can revert permanent cessation of heart and if you go advance again there are machines like Heart-lung machine(which can do the functions of both heart and lungs, it is mostly used in open-heart surgery) and ECMO machines ( extracorporeal membrane oxygenation ). It can also make alive a person if heart and lungs are completely stopped working.

Then comes to the brain, in brain death also a person can live for years by the life support machines like Ventilator. The question comes here that actually where life stays? how could you know you love one actually dies?

There is a possibility also human being can be immortal one day, There are many research going on the head transplant and to stop senescence (death related to aging).

What organ you can donate/ organ life after death

One man can save 8 lives by organ donation and can save 100 lives by tissue donation.

You can donate heart(1 life), liver(2 life), 2 kidneys(2 life), Lungs(1 life), Pancrease(1 life), Small intenstine(1 life) so, you can save 8 life.

You also can donate tissues include skin, corneas, veins, heart valves, tendon, ligaments, and bones.

What happens to your body after death

Pallor Mortis – It is the first stage after death, It is characterized by the paleness of skin due to collapse capillaries and blood goes downward by gravity. It happens usually within 15 to 120 minutes.

Algor mortis – it is the second stage of death, Reduction of body temperature as compared to air temperature.

Rigor mortis – This mainly due to anaerobic glycolysis without the presence of oxygen. it is the third stage of death, it characterizes by limbs have become very stiff and difficult to move.

Livor mortis – Livor mortis characterized by settling of blood in lower dependant area, due to cessation of heart function.

collection of blood in the backside (livor mortis )

Decomposition – Tissue starts broke into smaller part and give a very unpleasant odor.

Skeletonisation – This is the end stage of decomposition, where all tissue departed from bone and only bone remains.
