A method of hypothermic resuscitation is one of the most interesting and promising areas of medicine. This technique allows patients to be successfully revived even 40-50 minutes after cardiac arrest. The essence of applying cold temperatures lies in the fact that cooling the body slows down metabolic processes, which means that cells require less oxygen, giving time for the rescue process. Hypothermia is not a new phenomenon, as it has been experimented with in various animal species, such as pigs and mice, since the end of the last century. In humans, the method has been particularly applied in cases of cardiac arrest that occurred under extraordinary circumstances. Natural cooling, which…
