Here is what you can do if someone requires CPR:
A heart attack generally causes chest pain for more than 15 minutes, but it can also have no symptoms at all.
The danger from an electrical shock depends on the type of current, how high the voltage is, how the current travelled through the body, the person’s overall health and how quickly the person is treated.
The levels of bleeding may vary and not all may need medical treatment; however it is important not to take any chances.
