Drowning usually leads to death in a very short time, according to relevant medical studies, death is possible within 5 minutes, the mortality rate is 10% in 5 minutes, it can reach 56% in 10 minutes, it is possible to reach 88% in 25 minutes, and almost close to 100% death in more than 25 minutes. The Drowning International Resuscitation Alliance has a definition that if a person falls into the water, the process that leads to respiratory dysfunction and eventually leads to damage in all areas is called drowning. After a drowning person falls into the water, the water enters the lungs, and the airways in the lungs cannot exchange with the outside properly, so the damage is mainly caused by hypoxia, and the most serious of the hypoxia is cerebral hypoxia, and drowning often shows the process of asphyxia and cardiac arrest. The age of the drowning person, the time of being found, the time of being resuscitated and the temperature of the water may affect the resuscitation process, especially when drowning occurs in icy water, the relative survival time is longer. Therefore, any drowning person found should be resuscitated in a timely manner, and the rescue time should be as long as possible.
