Future technology. Resuscitation is one of those topics that is regularly discussed in the world of science. Resuscitation is highly unlikely at present due to the lack of the needed technology for success. However, it might be possible in the future as science and medical technology progress at a steady pace.
Bringing the dead back to life
Everything seems possible with the bright future that science has and it can rely on efficient outcomes, such as possible resuscitation, with its super and vast area of knowledge.
However, bringing-people-back-to-life is clearly a difficult topic to discuss as it touches the bare essence of life. Many people believe, for their own reasons, that the dead must stay dead. Science, on the other hand, responded that overcoming death might be possible in the future though.
Resuscitation
In the present doctors try to resuscitate someone right after they had a heart attack and died. They do this by performing either
(1) CPR (cardiopulmonary resuscitation – a medical treatment in which you breathe air into someone’s mouth and press their chest repeatedly in order to make them start breathing again and make their heart start working again).
(2) or defribilation (a piece of equipment gives the heart an electric shock to make it start to beat normally again).
These are emergency procedures performed respectively in specific situations. These methods are based on the gravity of the situation and may or may not work. Success is not guaranteed.
If none of these methods work then death is a certainty and all that’s left is to hope the required technology will be available in the future to bring the dead back to life, so to speak in this scenario.
Cryonic Preservation
Cryonics is the low-temperature freezing (usually at −196 °C or −320.8 °F or 77.1 K) and storage of a human corpse or severed head, with the speculative hope that resurrection may be possible in the future.
Cryonics procedures can begin only after clinical death and cryonics “patients” are legally dead. Cryonics procedures may begin within minutes of death, and use cryoprotectants to prevent ice formation during cryopreservation. It is, however, not possible for a corpse to be reanimated after undergoing vitrification, as this causes damage to the brain including its neural networks.
The first corpse to be frozen was that of Dr. James Bedford in 1967. As of 2014, about 250 dead bodies had been cryopreserved in the United States, and 1,500 people had made arrangements for cryopreservation of their corpses.
Economic reality means it is highly improbable that any cryonics corporation could continue in business long enough to take advantage of the claimed long-term benefits offered. Early attempts of cryonic preservations were performed in the 1960s and early 1970s which ended in failure with companies going out of business, and their stored corpses thawed and disposed of.

Afterword
Cryonics is regarded with skepticism within the mainstream scientific community. It is generally viewed as a pseudoscience and its practice has been characterized as quackery.
