Viral Sach: Can a dead person be brought back to life?

New Delhi: It is being claimed in a viral message that says if a person dies due to drowning, he could be revived if his body is found within 3 to 4 hours. The message is attributed to a man named Prashant Tripathi. Two numbers were being provided. The phones were out of reach. But we investigated the claims made in the message.  We talked to Kaushal Mishra of Primus hospital. He said a person who is drowning inhales water in lungs in a bid to breathe. Oxygen supply to brain gets snapped and person dies. In this condition, if a person is coma or unconscious, chance is that person could be revived. However, the time to do that is very limited. However, once a person dies, it is impossible to revive him. The message is false.
