If lightning hits the head and passes through the body to the ground, it will paralyze the person's nerves and heart, which may be fatal. After a person is struck by lightning current, the heart will either stop beating or beat at an extremely irregular rate and tremble. Both of these situations will stop blood circulation, cause brain nerve damage, and the person may die within a few minutes. If clothes catch fire, you should lie down immediately to put out the flames so that the flames do not burn the face, otherwise the injured may die from lack of oxygen or burns. You can also pour water on the injured person, or wrap him in a thick coat or blanket to extinguish the flames. If the person who received an electric shock has fallen into coma and stopped breathing, he should be asked to lie down on his back, unbutton his clothes, and immediately carry out resuscitation and rescue operations. While performing mouth-to-mouth artificial respiration, perform chest heart compre ssions. The essentials of the action are: overlap your hands flat and Place it on the middle and lower 1/3 of the sternum and pre ss vertically.
