sähköshokin

Sähköshokki, often translated as electric shock, refers to the physiological reaction caused by the passage of electric current through the body. The severity of an electric shock depends on several factors including the voltage, current, resistance of the body, the path the current takes through the body, and the duration of contact. Even low voltages can be dangerous under certain conditions, particularly when the skin is wet, reducing its resistance.

Symptoms of an electric shock can range from a mild tingling sensation to severe burns, muscle contractions, cardiac arrest, and death. The current passing through the heart is particularly dangerous and can disrupt its normal rhythm. Burns can occur at the point of entry and exit of the current, or internally along the path of the electricity.

First aid for an electric shock involves ensuring the source of electricity is safely disconnected before approaching the victim. Once the power is off, if the person is unresponsive, emergency medical services should be contacted immediately. If the person is conscious, they should be kept still and reassured while awaiting professional medical attention, as internal injuries may not be immediately apparent. Prevention is key, and this involves safe electrical practices, proper insulation of wires, and avoiding contact with electricity in wet environments.
